I was wondering what i should do about clutching. I frequently ride at 7000 and above but sometimes go riding at 2500ft. I ride a mm, power inc pipes mostly stock. My question is it worth buying the heel clickers or should i but another set of 8 cr's and have two seperate sets for the different altitudes. Also are the heel clickers easy to to tune or is it a constant tuning on them to get them right. any info on heel's or anything else helps thanks alot
