Stealth 2 shorter than SIM 2?

[Scott Lyons]

Fitting question I can’t seem to get a good answer to. I have a 8 degree sim 2 driver with Ventus black 7x TR shaft. I recently bought a stealth 2 8 degree head thinking it might show a little advancement. I found the new head shorter and spinier (600-700 rpm more spin on GC3). Have you seen any situations where the carbon face or something else with the stealth 2 to cause this? (Avg swing speed 123mph seeing differences of 10-15 yard shorter carry.) thanks as always

Swinging that fast it can be the most small things in strike and swing characteristics that can change spin that much.

Could be as simple as the profile of the Stealth 2 is causing you to hit fractionally Heel or low causing that spin to climb.

Yea. Certainly could be the case. These were 15 shot averages, but I did remove the outliers

Hmm I haven't noticed much of a difference between my SIM 2 Max and Stealth 2 (both 10.5 and almost identical shafts).  However, I just got the Stealth 2 last week and have only had it out a couple of times. BTW I much prefer the sound of the Stealth 2.

If I recall one of the knocks on the SIM and original Stealth drivers was forgiveness and I know a focus they put into the Stealth2 was forgiveness which spin adds forgiveness so that could be by design. But as @GolfSpy_APH said a small difference in strike or face angle could be it as well.
