I had read on the pdga message boards about a tweak with the r pro plastic...apparently they've added wood composite, which is supposed to add grip to the disc, similar to the old school special edition rhinos. They have an rw pro aviar, rancho roc, and ontario roc on preorder at www.discgolfvalues.com
and won't ship until this upcoming monday, the 27th. They're supposed to have a woodlike color to them, and smell like wood also. I went ahead and ordered one...should arrive a few days before the Open if I'm lucky. I finally handled one of the r pro aviars the other day, and if the rw pro is similar in flexibility but with more grip, it's gonna be a sweet putter.
