How bout the HLSD, do you notice the grip different. Also i would try a little lighter gear oil if your running straight Shockproof. Give the 85w140 a try, its cheap. No synthetic just the standard 85w140 valvoline gear oil. Save your shockproof so that if you dont like it you can put it back in if your concerned about wasting it. Give it a shot and tell me what you think.
