To get rid of traction rolling basically take away steering. What alot of guys do at big races is they will superglue the sidewalls of the tire to keep the side wall from delfating and causing a traction roll, q-balling is pretty much the same deal (since you are talking away the sidewall, lol) and probalby some of the contact patch.

Speedo... I personally have always been very happy with my quantom compeitions. I really want to find one of the new ones before Cleveland so I can test it out and run it (so if anyone knows where I can get one at my frontdoor within a week send me a PM! lol). However, the old quantom comp should work as good as anything out there.
