I just moved to GA. from Fla.. My starcros ms3 front washes out on the hard pack flat corners. I think I miss railing a sand burm. Here its either flat hard pack or two tacky rutts through flat hard pack, no burms. I'm thinking of trying the 90/100/21 bridgestone 601. or dunlap 952. Doesnt suzuki and kawi use the 90s instead of the 80/100/21 . Is there an advantage?
