i've only thrown 3 Rhynos.... I'll swear by them and give you some advice from what i've seen / thrown... (I currently throw a CFR "Gummy Champion" that folds like a taco on impact... it enhances the Rhyno to be what you always wanted it to be. It's like a putter that can be thrown as an approach disc. When it hits anything it stops dead.)
Rhyno -
"When you would rather throw a brick, want to lay it on the ground and keep it from rolling."
-> I use the Rhyno when i'm shooting uphill, or the pin is on a steep hill with a lot of potential for an evil long roll when the disc hits the ground.
Pro: The benefit of this disc, is that the more it gets used, the floppier it gets. Once it gets beaten in, it loses some of the rigid feel and does become slightly floppy and gains Chain Love...
Star: Couldnt tell you, it's still a rigid disc (See Champ Review).
Champ: For me, if you arent going to use a "floppy" (Pro) Rhyno you really should get a Gator. Unless you are really throwing the Rhyno hard, it will feel and throw almost exactly like a slow Gator. (eg. The Gator hits the chains, the rhyno would clank on the top of the basket.) Both will stay on the ground next to a target, have little skip or roll, and fly very similar in putting and non "hard throw" (driving) situations. To me, when thrown hard, the two are the same except the gator flies 1.5 times farther. Great for Wind and Uphill Shots. The Rhyno isnt a sidearm disc while the Gator is one of the best short range discs i've found.
(I suggest anyone to get either a Gator or Rhyno, both can be game changers for the "less than" experienced amateurs and pro players.)
