Hey Ryan,
It is funny when I watch people try two handed, and I am no exception. All side rotation and no forward rotation. What I found when I saw Belmo bowl up close for the first time was the amount of forward roll he has is amazing. The power is unbelievable.
One handed thumbless guys are the same, side roll. Mike Miller probably the exception with a fair amount of forward roll but gentle and smooth.
Mr George I have seen throw a few two handed shots, he gets pretty good forward roll, so let's hope that young guy doesn't start doing it more often.
