I'm running Prism T rear and Swaggers on the front, which seems to be a great combo. Some of the other guys are running Pin Downs and Swaggers with good results as well. I can say I was not a fan of the Prism T fronts - they were too edgy. When I ran Pin Downs on my ST, I couldn't get more than ~2 race days out of them, so I'm hoping the Prism T rears will last a bit longer - so far they're still looking good after 3 race days.
