Effective Loft.........and adjustable Drivers

[CMAC]

Must admit I hadn't come across this before and still getting my head around it.

I've gone from an 8.5* driver to a 10.5* 1 degree open driver and its a joy to hit. I was worried about ballooning with the extra loft and without my 'Low Launch graffalloy red shaft' but the flights are better launch, more air time and more distance:thup:.........why?

Apparently a 10.5* driver with 1 degree open is effectively a 9.5* driver
Conversely the 10.5* driver you bought and adjusted the face to 1 or 2 degrees closed because of your slice, is now a high ballooning 12.5* driver....or it might be, dependent upon shaft etc but the fact is it's now effectively a higher loft even though you CLOSED the face.


So basically if that new driver has a closed or open faced option, or if you have already adjusted the face closed and wondering why its higher and weaker now, then maybe its a good idea to get to a launch monitor and see whats right for you.


This all might be old stuff for you but it's new to me and thought it might be useful to some

i thought this was in the case in the original TM adjustable drivers (r9) and was under the impression the new type r11 had independant adjustability so that open and closing the face angle didnt alter the loft.

None of these adjustable drivers are truly independant on ther loft / lie adjustments. Some are closer to it than others though.

Your 100% bang on, people have this perception of an open face of an adjustable driver to be lofted like what you do with a wedge which is not the case.

That was certainly my perception, so the 12 draw biased driver I occasionally drag out with me is in effect actually about 14 degrees? Or to put it another way a 3 wood with a slightly longer shaft.

Unsure because it's made like that unlike the adjustable drivers where your change does it.

Check this post out from one of the Team Titleist fitters

No it is no possible to actually change the loft of a metal wood head, (this is because the sole of a metal wood is long enough from front to back and will sit the same way on its sole no matter how you angle the shaft coming out of it, to actually change the loft of the club you would have to mill the face down) all the bending or SureFit Hosel adjustments are changing face angle that changes the effective loft of the driver (look at any of the tables and in small print below it says EFFECTIVE LOFT when face is returned square at impact
for every 1* open you make the face the effective loft decreases by .6* less. therefore the .75* increments that Titleist has been advertising means the face angle actually changes by 1.25* ( .75 x 1) / 6 = 1.25
therefore your question on if the stock driver is 9.5* at .5* open and you change it to 10.25* of EFFECTIVE LOFT then the face angle would become 0.5* - 1.25* = .75* closed
if this whole post was too much for everyone to take, just remember it is no possible to change the true loft of the face on a metal wood just the effective loft.

It is if you open the clubface but then have to square it up at impact: eg close it again. I'd rather open it up and LEAVE it open at impact... more effective loft and better launch angle.

If you close a club taking the loft off then it will launch lower...but not if you spin it open again to square it.. you've then added the loft right back on. You need to know your faults and predicted shot shape before you start tweaking... it's rather funny isn't it? considering most golfers haven't got a clue what they're doing with NORMAL clubs

its already 1* Open, you don't need to do anything except put a good swing on it

Isn't that what I said?

This is the best explanation I've seen for me thinking My 910 looks closed to me when I up the loft to 12°.

I mentioned it here about a year ago and I felt like I was cracking up because no-one else had noticed.

eh? Now you've lost me.... you should be opening the face to add loft, so it shouldn't be looking closed unless you are then addressing the ball with the face square (eg opening it then rolling the face closed)

no! you said

"I'd rather open it up and LEAVE it open at impact"

its already made 1* Open and a good swing will return square making the EFFECTIVE loft 1* less​

Ah.. right ok. I don't want a square clubface. Open clubfaces are made for the better player to shape the ball easier It makes it easier to push... for push-draws and push-fades.

The quote above from the Titleist chappy says that for every 1° open you make the club you lose 0.6° of effective loft.
So it follows that closing the face gains loft, ergo, gaining loft closes the face.

No?

This kind of makes me even more certain that adjustable clubs aren't for me. Apart from being too much of a tinkerer I'd rather know what my club is set at and just blast the bloody thing rather than worry if I need to hit it with and open face or if my swing will counter-act the closed face my 067% and effectively put 351rpm less spin on the ball

 

[CMAC]

I'm not a fan either Homer, I'd like to be fitted and then do things with the swing to shape the ball if I really have to. I don't mind the weight tinkering ones though like the MP630 FT and the Razr Fit etc

My main point was the 10.5* I have is effectively 9.5* if I swing back square (which we all try to do I believe), which pleased me as I felt 10.5 was too high as I like a penetrating flight ooeerrr missus! but my flight is just that, happy days
