Can You Handle 12'-14' Dia. Balls?

From the pictures I've seen... there sure are many 'rollers' out there.

We seemed to have some trouble rolling balls with the min. and max. diameter.

We made sure that our balls ranged from 12in. to 14in. dia, across the seam. Some of the 12in. balls wouldn't roll up our chute so easy, and some of the 14in. would stick at bit.

We will be bringing our 'calibration hoops' to Competitions, just to see what size balls we will be playing with. Hopefully, we have allowed for the worst cases.

From the wide variety of shooting % that I've seen so far, I'm thinking that some teams did not inflate their balls to 14in. dia. I'm thinking that the balls would stay better if they are toward the 12in. dia (smaller, plus less bouncy).

Remember that the spec is 13in. +/- 1in. across the seam!

So, how did your rollers fare with this drastic deviation in diameter?

Andy B.
