I have been using Max-Torque and the ARC Mongrel clutches where shoe clutch is required, which is frequent. However, I want to upgrade to the best shoe clutch I can get to improve my starts. What do you recommend? I run 375# classes, sometimes Maxxis HT or EL, sometimes Burris. Box stock clone with pretty much blueprinted everything (build my own engines), big pipe, PVL flywheel, BSP-3 cam. So what do you recommend for the best shoe clutch?
