Thanks Jimco, I go to OCRC as well... My set of tires on my B44 were the double dees. It didnt' feel like they hooked up as well as the Holeshots there (Holeshots LP R3 compounds were my second set that are now worn out), but perhaps I should revisit it. The difference between Holeshots and Double Dees in terms of hook-up at OCRC if I remember correctly is like the difference between 1" and 1.05". They were very close tie.
That's what I've been hearing from other B44 guys also, that Double Dees lasts longer. Perhaps it's worth another visit...
