Personally, I like the CG to the right of the mb and pin. This tpye of ball is stronger in the midlane and better on an oilier condition. Is the mb to the left of your thumb..? This could be why the ball is lazy.
Also, check your statics, as they could add a little kick if used correctly. Meaning bottom weight, thumb weight and zero side weight will make the ball a bit more lazy. Adding more positive weights could help on drier conditions. =:^D =:^D
