David,

Let me know how it goes. I spoke with Roger and he said he was not convinced that the R6 tire would have more grip. He did not know for sure. He did say the R6 should last longer but only a few heat cycles. I get about 8 heat cycles out of the bias ply goodyear slicks and they are out of grip in back. On the 9th or 10th heat cycle, its dicey and getting to the cords sometimes, so I pitch them at 8 cycles.
