I'm going to go get a ball fitting finally at a local shop. (Don't know why I waited so long!) So a couple of questions to those who had their's done.

~What should I exactly look for as far as the specs and numbers?
~Do I need to pick a brand first then try their different models?
~Let's say I was fitted for ProV1's and it's the best for me, would I get an alternative choice? (not to sound cheap but 45-50 is a lot for a dozen)

Thanks guys!
