I run Avid Shorty 4's They squealed and juddered with the stock pads mounted. I switched them out for Kool-Stop's dual compound "Mountain Pads" and beaking performance has improved greatly. The squealing has been eliminated and the juddering (which is something i experienced on my un-suspended MTB) has been greatly reduced-- almost eliminated. Braking is smooth and progressive-- never grabby.
One note-- Kool-Stop's instructions call for a cleaning of the braking surface. This is a good idea as part of regular maintenance, anyway.
Toe-in is more important on brake pads where the brake shoe is symmetrical-- the post is in the middle of the pad. Kool-Stop's pads are asymmetrical-- the post is closer to the front of the pad.
Even so, the Mountain Pads have a molded in rim "sweeper" at the back of the pad that sets the toe for you.
I can't recommend the Kool-Stop pads highly enough.
(And no-- i don't work for the company.)
