I got my updates installed and took the bike out yesterday. I agree with Timberview above, it was hard to tell if the updates helped or if the well setup spring snow kept me from trenching. I did notice that I no longer feel the metal/metal contact from the rear slider when going over whoops, etc. Unfortunately, I still have buyers remorse. (My wife's '14 Timbersled LT hooked to a KTM 350 has far outperformed my YZ450 MT 129" all season long- every time.)
