Guys, just can't automatically assume it's a bad fitting - if the AoA isn't great and the strike location is all over the show (no disrespect OP ), then the fitter only has so much to work with.

We need more data to opine on an informed basis, but safe to say that switching out a Rogue for an Ad-Di or a Devotion or even a Kiyoshi Black isn't going to find the OP 1000-1500rpm...

Do you not think though that a good fitter would have discussed AoA, ball position etc etc? Mine did.

Discussed? Yes, absolutely... completely agree.

What size tee do you use?

I tee it up with about 1/2 of the ball showing over the top of the crown.

would say the thing to look to first off, assuming set-up is all good, is strike - (as the type of shaft to swing speed looks to be in the solid ball park area of fit)

given that the spin rate is little ways over optimum so too the peak height
as at 3400 with that CHS that's well over a 1000 rpm than would be around a realistic optimum of say an approx ball park 1900 to 2200, and at 40 yards PH that's approx 10 yards so 30 feet higher than a reasonable ball park figure - given you are definitely sure (through monitored LM numbers) you have a pretty reasonable +AoA
would for sure monitor just where the strike location is with a can of spray
strike location has to playing into those spin rate/peak height #'s

would say it's more likely to be a strike location issue along with perhaps with AoA to LA, so between them the spin loft angle is too large hence the spin and height issue - wondering if that AoA is perhaps more down than you think

ideal strike location just a fraction above the driver face equator, with just a fraction to the toe side of the vertical center - with bulge and roll of the face there's only a small area around the center that's the true loft of 8.5 - may sound counter-intuitive but that loft could well be a tad too low possibly

plus as eluded too previously in posts - tee height/ball position - will play into strike location

best ways to monitor for real would be GC2+HMT - looking at strike location plus AoA/LA

My strikes are generally pretty good but slightly more towards the heel but quite central and I have a very in to out swing path. I am also pretty short at 5'7.
Practicing tonight the ball position is definitely a good inch or so inside my left heel. I seem to struggle with accuracy if its further forward and hook it terribly.

Did the fitter not discuss spin rates as he was doing the fitting. The spin rates do seem too high

Ye he did but its more my swing as other clubs produced higher spin rates.

110mph ss at 5'7", there's hope for me yet!
