I would say that you would be fine to use a Rhyno for all putts, up shots, and most of your drives of 500' and in. Follow this advice and you will soon surpass what you once thought to be your maximum disc golf potential.
Seriously though, I use my DX Rhyno's for the majority of my up shots, aside from the ones where I need to avoid obstacles by going around or over them. I do 90% of my putting with an extremely beat in DX Rhyno, and left to right up shots from 150' and closer I use the same disc. Hyzer approach shots and head wind putts I tend to use a newer, more stable version of the same mold.
Please take this information lightly, for I am very biased when it comes to the Rhyno. Try one though, they are sweet dude.
