The LT2 is just to heavy for average trail riding.
Built up my Blur LT is 27lb. I don't think the LT2 is any more on the frame weight. If your lower link is creaking you need new bearings on the old Blur. When did you last pop the pivot axles out and grease them?Really? I can't imagine the frame and shock being more than 6, maybe 6.5 pounds. How light do you need it?
