carlo,

i think what you need to understand first is why you are slicing the ball.  what are the mechanics in your swing that's producing a slice and what is the path of the clubhead coming into the ball?

for me, i have a slightly over the top flip that creates a shot that starts left and draws from there - pretty bad combination.  so i adjusted my 910d3 clubhead to b-1.  the open clubface counteracts my flip and provides more of a straight shot instead of a "start left and keep on going left" shot.

in my 17* hybrid, i've set it to c-1 to decrease loft (since i use it as my 3 wood) as well as straighten out my left draw. 

hopefully all this will change if i have time to work on my swing mechanics over the winter.  good luck to you!

I wasn't fitted for the driver... it was one of the things wherein I didn't like my old driver (909D Comp) so I just wanted to buy the latest Titleist driver. I bought it a little over a week when it came out last year (either that or a snow blower). I spent a good amount of time hitting the D2 and D3 plus the different lofts and shafts they had. I based my choice on feel and results (simulator). No regrets though...
