I bought a set of sticky Roxzillas last year and love them other than the wear. I need to replace them and I'm considering the standard version. Is there a big difference in grip between the sticky and standard Roxzillas? I ride Eastern TN mainly. I've got a set of Xcomps on another set of wheels that I switch out when I take the kids/family, but I just hate to watch the tread literally wear off as we ride.
