Were up riding probably last ride. Have my VR1, Launch 850 137, Launch 850 129, Launch 650 137 and Assault. You can feel the difference in as shock package between the VR1 and Launch sleds when you ride them back to back. I'm still up in the air between a 850 VR1 137 or 850 XCR 136. Bontz ask Chris if they sprung the XCR different from the VR1 or valving on the shocks or both?
