Another report. I sold the 12º 915D2 and bought a 10.5.
These drivers sit open at all adapter positions except the highest loft/most closed setting, where they sit dead square. I kept trying to play the 12 in the neutral or intermediate closed position, but I was fading the ball too much. I'm no good at hooding an open faced wood so it sits square at address. I just can't do it, there is something in the balance or whatever.
When I set the 12 fully closed, then it was too high in loft. Hence the replacement is now a 10.5 set to 12. I have high hopes for it, but haven't hit it. I bought it on the 20% off ebay code the other day. 🙂
