Yeah I would be curious to see what they each do differently too. I almost had 350x do mine but went with cam. No complaints at all. I know he does mod the shift shaft as well, bearing added to the drum, cut what looked to be every other dog off the gear. I didn't realy take it apart after getting it back. Just installes it. Cam never realy said EVERYTHING he did to it....secrets of the product I guess. Don't want to let everyone know what he does to it exactly. I do know it shifts awsome now though.
