Pro X suspension

Hey is there anyone here know how the pro x rear suspension is different from the edge suspension(other than the shocks).If anyone knows a good initial setup for cross-country& agressive trail riding for a 170 lb. rider, let me know.I may do a little drag racing too, but I know some local boys that know all about how to set up the suspension for that.I'll mess around and experement to get it right, I just thought someone might save me a little time getting it in the ballpark.
