If you don't mind the plastic, R-pro is the way to go, they pretty much sit where they hit and they are great in the cold and wet. When it's hot out, I sometimes switch to G*. I've become used to softer Rhynos.
I've never thrown a R-pro Rhyno but have thrown plenty of the other blends... I do have a R-pro Pig that I absolutely swear by...
Until recently, I was throwing Rhynos in Champ and Champ Glow as a main part of my bag... when thrown well, they are fantastic discs... Very reliable
