I haven't heard of any reliability issues with USSSA models, so the return issue doesn't really come into my thought or made me consider the pricing out of line.
I really like the balanced nighthawk I have been swinging at 26oz. I have another in 27oz as potential backup but won't likely need it. I would like to try to Robo Load. I haven't seen other Nighthawks used in my leagues, but they are probably there (or should be!).
I would buy another, but the one I am using isn't likely to fail/break. I would consider a new version, for sure. I think 2017 Mizuno offers could be interesting, but hadn't heard rumors. Thanks Shoe!
