Does anyone have any experience with how to prep these Unilli Tires? Looking for the best way to prep them both internally and externally, i have a roller and have several different lines of prep to use. I have heard that these tires take twice the amount of prep that you would use on a burris tire, but im not sure i believe that, they seemed to hook up pretty good on the track when i scuffed them in. They look and feel exactly like my maxxis Pink and Blues do, so im assuming you would do the same thing with them like you would a maxxis. Any help from someone that actually has experience and runs these tires weekly would be a great help, i have to run these in a class at the national races coming up this weekend and next weekend, so im trying to figure out what to do with them.
