Well i finally broke down and got the rear works shock (419$ from rockymountain) and let me just say now for the first time it rides as smooth as butter.I tried stock and the 400ex and now the works shock.When i first started my build i had won a works rear off of ebay.The guy shafted me on it so i just ended up going with the 400ex,ltz shock.Let me just say that it lets me run a lot faster over the bumps and stuff and it sets just right when digging into a corner.Now the place where i test run at im able to get another gear on my little straitaway.Really nice in the trails.After this i would say just save up and get one of these instead of the 400 if you are serious about riding fast in the ruff stuff.A++ I:I
