I came to a conclusion as well my XTX is a must for a re-valve of all shocks. I'm already running Triple rate springs in front and handling has impressed me thus far. However, coming off an Apex Gt with Pioneer re-valve on rear Ohlins shock the XTX is light years away from being as comfortable of a ride. The stock valving feels awful harsh in big bumps with font shocks bottoming occasionally. Smaller studder bumps the sled behaved well for the most part. Anything, over 8" made me cringe. Will have to consult with Pioneer, Hygear and Carver on a what their solutions are...
