Yes,  A-1 is neutral face... but you can change the lie independently.  

Ryan- I have an 8.5* D3 in the A1 position if I want to add a bit more loft I can move it to D4...but the club is no longer in a true neutral position...correct????

When you increase the loft alone, it has a tendency to shut the face. To counter this, you will want to also, flatten the lie angle so you are probably looking for position C4.

I have a 910D3 8.5* set at C4 since usually play 9.5*. That setting makes my drives "explode" off the tee. (buh dum tssss)

Get it? C4 explosive?

I'm sure you are laughing.

I'm hilarious.

do you have the 913 or 915?

Yes sir... technically not "neutral"... and like another member said, I tend to go to C4 more often than D4 during fittings.

However, the 915D3 is more open than prior generations so it tends to balance out.

Thanks Ryan!

I'll give the C4 position a try before I look for another 913D3 head in a 9.5.

Still Tinkering,
