For the first few years, I didn't like the feel either. I dunno, they feel natural now. The shallowness allows for a good release. Also, I agree, they aren't necessary OS. I have two rhyno shots (BH anyway)
1. 1-60% power: pretty straight to decent fade
2. 60%+ power: dead straight to a little fade if it runs out of steam or if it is thrown high.
Point being, I hardly ever flip one unless I am trying to (I don't have a big arm), so I feel comfortable laying into it. When I am running it at the basket from 100-150 ft. out (Option 2 above) I just point and shoot, because of the lack of glide, magical things happen.
Several poster have said that pros just power down a mid or can throw a beadless PnA on the same lines as Rhyno. You guys are probably right. It's not like that for me. I don't want to power down a mid, it's probably too much glide. I just want to crank on a approach, know it's not gonna flip, and it to finish straight or with a slight fade.
