Excellent cams but the x4 and x14 are usually much too aggresive and top end oriented for trail riders running low comp machines.

 

With my 10.75/1 JE and a stage 1 Hot Cam I had more low end torque than necessary for trail riding. Fighting to hang on from to much torque will wear the rider out much earlier. The stage 2 cam looses a bit on bottom in return for more on top. Much easier to ride and more power where I like it.
