I was pretty impressed by how capable the SB100 felt on the descents despite its short travel.  I got a chance to ride the Yeti SB100 earlier this year back-to-back with the Yeti SB 4.5, Santa Cruz Tallboy, and Pivot Trail 429. It was definitely enlightening to be able to ride all of these bikes on the same trail on the same day.
