the problem with the klaws is that the lugs are too close together and dont allow for a very good bike, especially when dragging. if you want to make klaws really hook up you have to cut every other row out of them. the knarlys lugs are further apart allowing for a better bite. i run a set of cut knarlys on my silver banshee. they hook unreal and unless you have some power to turn them youll prolly either have to start in 1st or end up on your ass. i would go for either the knarlys or the mx knarlys. Irazrs are a good tire but too heavy for dragging as are itp holeshot hd's. i dont care for regular razr type tires myself. i find they dig holes more than anything.
