I need to ask everyone here a question because I'm about to give up on Spitfires for good which sucks because I've always ridden them and they're my favorite wheels...I'm regular and for some reason my back, toe side wheel always cones/gets worn down way faster than the other three. Has anyone else ever experienced this? Right now I'm riding the 53mm/99a "What, Me Spit?" and it happened so fast. I flipped it over and it coned again. I don't do a lot of powerslides, and admittedly the ground here is pretty rough (even the formula fours that I've had have worn out really quick!) I skate once or twice a week, usually for a few hours, and I feel that a set of wheels should last me a lot longer than Spitfires have been lately. I've had this set for a month and a half and the size difference in the one wheel is huge, not to mention all of the chunks and divots missing out of them from the rough ground...
