I like the top mount, but if im not using the bar risers, than i would need a different mount.
i have clip ons and i use the top mount. i like it better than the side mounted stuff. I can adjust on the fly plus if the bike tips over, i wont smash 500 bucks.
It is a lil funny looking since it attaches to one riser. But it works so well that i can forgive it. You barely notice the riser since a shiny damper is right on top of it.
