It is definitely not too large, looks good.Thanks for the feedback. I'll try the group 1 value from 2.0 now that the roll friction is taken out and see how it goes. 2.0 has a group 1 value of around 0.390 which is the heaviest (and largest size) of the lot. The extra weight should feel the best I'd say too. Do you find the ball looks too large or is it ok to your eye?
