I'm really wishing I would have brought my RR's this past weekend to compare...
I always got my RA1's shaved to 5/32 and could get 3 events out of a set (flipping after each event). I felt like they had the exact same grip for the first 15 heat cycles. They maybe dropped of 1/4 of a second at heat cycle #20 and really starting losing about a second / lap around #25.
