I knew robert smith has to drill his ball with middle finger to zero side pitch,
what is the main purpose for this ? more may I know why he use so many reverse pitch to his finger ? almost 3/4 !!
if I have a span of 4 3/8, it is too much for me to put 3/16 reverse pitch , my thumb pitch is 1/16 reverse, I feel I can go to 1/16 forward as I shorten my span from 4 1/2 to 4 3/8 and I use 1/8 under palm thumb pitch too.

hope some one can help me as I feel my ball always want to get out before it go to the bottom of my swing and it let me squeece the ball often.

I will further move my thumb more forward as I already felt I shoud go for that.

and folks, what is the answer of my first question why rober smith move his middle finger to 0 instead of 3/8 (standard) ? it is mean for more turn? if I change the middle finger to 0, should I move my thumb slightly under plam ?

thanks for yours reply
