The HH guys have been fast with what appear to be box-stock C2s. Then again, Ive heard good things about the reedy 19T spec, and Ive seen some of them run, theyre quick. I think the C2 setup the HH guys had was box-stock, and the Reedy seyup was 767s with Trinity purples. I think for 1/12 they used reds. But for touring, I think purple was the ticket.
