I have a 05 F7 with 96 studs and the stock track. I'm looking at getting new carbides. I would consider myself an aggressive rider and I ride completly state trails in Minnesota which are quite curvy. I have 3 questions with this basically, dually or not? which brand and type of carbide are good for an aggressive rider? and also what length of carbide would be best? I've been looking at forums but thought I would post something for my specific situation. Thanks a lot everyone.
