Im currently riding a Cowan DS w/ Progressive 5th Element and I want to upgrade the rear shock. I cant decide if i should stay coil, or go air.So your opinion's welcome and encouraged! Currently under consideration is DHXair/5.0 , Rp32, new Rock Shox. Bike is used for southeast DH/DS/and general trail riding, and will go to Snowshoe. Lyrik 2-step on the front.
