It is hard to go with anything other than Works. My little guy beats those shocks all the time, they are bomb proof. The extended ones, I think have too much spring. As those shocks are jumped more and more, it is going to act like a pogo stick.
That is what we want to get away from.(the stockers)
Plus the works are rebuilable. I'm getting ready to get my boy the heavier springs from them. He is right at 55 pounds with all of his gear on.
If you are in good with someone that works at a shop, ask them to do you a favor. WC has an "industry insider" program. They can get you a set of shock for a big price cut.
