i finally went for the trackman session today and i thoroughly enjoyed it.the experience itself was good and the information you find out is unbelievable,everything from swing/ball speed to attack angle and much more.

the main issue i had with my current driver was the flight i was getting.i believed the height i was getting was too high and that i was getting far too much spin because i was getting not very much run on the ball at all.even on firm fairways,i would get some but not what you would expect.

i went to scott gourlay at craigmillar golf club and he is very good and knows his stuff.because of what i told him he brought another driver along which had a stiffer shaft,he believed that the stiff shaft fitted to mine was too soft at the tip for me and causing the clubface to come into the ball with more loft.the other driver was a callaway ft(i think) 8.5* fitted with a matrix ozik x-con 6 shaft and my driver is a titleist 905r 7.5* fitted with a grafalloy blue stiff shaft.

the drives with my own driver were as expected quite high and the spin rate and launch angle were also high.the landing angle was soemthing like 40+ degree's with my own driver so roll out was not that much.

immediately with the callaway driver the numbers were much better,spin rate was down below 2500rpm with the average being around 2200rpm,my ball speed was up aswell averaging about 160mph with my swing speed being around the 110mph mark on average.

i hit quite a few bad shots with both drivers but with the callaway there were fewer bad shots but when they were bad they were left,but i felt like they were good.what was happening was at impact the clubface was lsightly closed and this was due to the matrix shaft being slightly soft for me so scott belives a slightly stiffer shatf will improve my numbers even more because with my titleist i couldn't get the ball speed upto what i could achieve with the callaway,i was losing about 4mph on average with the titleist.

my best swing with the callaway had me at 114mph ss but i only managed 165mph ball speed because i caught it off the toe.....good thing about that was it had reduced spin rate and ran for ever.

i'm not entirely sure what all my numbers were because i'll have to wait for scott to email them through but my average carry distance was in and around 265-270 yrds with total distance being 309 yrds average.

i was teeing it lower than usual but i reckon this may help with getting more roll out,my attack angle is good though at 4 degree's so i'm also striking up on the ball which should create a lower spin rate....

scott's going to get a few shafts in for me to try then we're going to take it from there,i'm in no rush but the plan will be to have a new shaft fitted before the start of next season.
 
Sounds impressive.

You could end up with a hideously expensive driver though!

yeah that's the downside,but because of this scott wants to be absolutely sure that the shaft i go for is the best one for me....and gives me the best results.i hope it's not too expensive but i'm willing to go for it because i'd like to hit more fairways and improve my scores.
 
Doesn't a swing of 114 mph and a ball speed of 165mph equate to a smash factor smack on the magic 1.5 which i thought was the holy grail of driving?

Interesting results, I tried the Mizuno 630 with fubuki s shaft and immediately brought my avg 3000 spin and 11* launch on the Titleist 907 8.5* down to 2400/2500 spin and 9.5* launch.
My swing speed also went up from 104 to 108 which averaged 240yd carry (all these monitors give diff results).

What was your launch angle and what shaft did he recommend?

from what i seen the smash factor was usually 1.50 and i seen 1.51 but it was usually around that.i wish i had struck that one sweet because i reckon the ball speed could of got nearer 170mph.these were all pretty normal driver swings,there were a few i tried to rip at but i never struck them well.

great read, I was fitted for a driver recently, my numbers are nowhere near yours but I really enjoyed the information given. The way different spins effect the length etc.
I am sure at your level with your numbers the correct shaft regardless of the cost will be a huge help in getting your scores even lower.
I look forward to reading about the shaft that works best for you and how you take it to the course.

when i get the email i'll know for sure,i think the email will have the recommended shafts attached to it but he mentioned a few of the project x shafts 7.0 and as such.

i was wary of what the yardages would be because of what people have said,fact is i knew before hand what my yardages were from playing so much golf this year on short par 4's and using gps systems but i was keen to know ss,bs and other factors like that.from what you've said though i would say your launch angle is a bit low and that's maybe why you are getting not very much carry.i think my launch angle was always above 11 degree's and my ball speed was always 160 mph roughly.the thing is if you hit the ball lower you have to have the ball speed for it to get out there,if it doesn't have the speed then it's going to fall out of the air and go nowhere.
 
i do enjoy the trackman sessions,however i am not totally convinced on the accuracy. i was on it this morning hitting my driver around 12 degree launch angle with a 7.9 degree launch angle in the mix with no swing changes.thought that was a bit drastic

good point maybe the 10.5* would be better for launch with that fubuki s shaft, a few mizzy tour guys use 10.5* with appropriate shaft and they are long. Big jump from my 8.5 to 10.5 but if I hit more fairways I'll score better
 
I have to be honest and say a lot of the shaft technology is like a foreign language to me. I like to go on these monitors and providing you get someone who knows their stuff then it does have some value. It sounds like you've got everything pretty much on the button now and so there will be no excuses when the new driver eventually comes if you can't find the short stuff. Enjoy

what was you attack angle or whatever it's called?i was managing launch angle's over 11 degree's with both the 7.5* and 8.5* and the 7.5* was going higher because of the weaker shaft.
 
i got the email with all the data but i'll give the average,i don't know how to post it up on here as it's pdf format.

club speed 108.3 mph
ball speed 162.4 mph
launch angle 11.8
spin rate 2287
carry 266 yrds
overall 284 yrds

the overall distances have changed from when i was there as it was showing up as 300+ on some of them with 30-40 yrds roll so obviously something has changed.

with my driver,the numbers were

club speed 105.9 mph
ball speed 158.7 mph
launch angle 11.3
spin rate 2326
carry 250.7yrds
overall 272.3yrds.

these numbers for my driver are from 4 drives but some of them showed up as being higher launch with a steeper landing angle and higher spin rate.

the recommended shafts are



Project X 8A4

UST Attas Series 7

Matrix 6M3 Tie X Flex

and also

project x 10a2 x+

grafalloy prolaunch red tour 65 x+

i can see it costing a few quid but i'm sure it will be worth it.
 
I wouldnt worry about the roll its saying, roll is very ground dependent obviously.

Also some of these shafts arent expensive so it could be a very cost effective change for you.

Punch your numbers in here for a comparison

i found a few that are selling for £200 on ebay but i'll wait and see when he gets them in.i like the look of the Matrix 6M3 Tie X Flex as it's quite light aswell.
 
The launch angle (11.8°) seems to be very low, if you look at flightscope and put in 160mph with 20° launch you'll be carrying 282yds, 12° launch only gives you 263yds. Just a thought for you to ponder :)

Golf balls nowadays are made to be hit high with lower spin.

i reckon this was down to the tee being lower.because of where scott was seated he was leaning over and teeing it up for me so i never bothered changing it.next time i'll tee it up because whilst out on the course today i was carrying it very high with a silly high ball flight.the 280 carry seems about right,all season i've been carrying it roughly that distance so it makes sense.
the spin rate will still be low with the higher launch angle aswell so hopefully run out can be achieved.

one of the trackman numbers shows 14.1 launch angle with 275 carry and the landing angle was 36.8 so still better than some of the 40+ landing angle with my own driver.

i don't want to have too high of a launch angle because the steeper the landing angle then the lss roll out i will achieve.it's a fine line but i think the stiffer shaft will help me and i can tee it high and confidently swing away knowing it should hopefully go pretty straight.

I don't fully understand this? Your stats have come back at 11.8 launch angle but only because you say it was teed too low at the fitting? Then surely it wasn't a "correct" fitting?

next time i'll tee it up because whilst out on the course today i was carrying it very high with a silly high ball flight.the 280 carry seems about right,all season i've been carrying it roughly that distance so it makes sense. the spin rate will still be low with the higher launch angle aswell so hopefully run out can be achieved.

OK, so you launch high to get longer distance. Fair enough. But the final stats and shaft recommendations are for launch angle of 12 degs...which isn't what you are doing on course as you are teeing up to get a higher launch. Thus, you don't know what your optimum ball stats are and thus what shaft is really right? And what about driver loft??

Apologies if I've really misunderstood or blatantly read between the lines badly - just trying to ensure that you are getting exactly what you need, rather than what you want to hear!
