WTB Rocket V is really popular, but I prefer WTB Silverado. Silverado is a different shape than the Rocket V--Silverado is more flat across the top, which keeps my middle section (if you know what I mean) off the saddle better than a rounder saddle across the top. Silverado is also very light--I think their heaviest model of the silverado is 270g; my model of the silverado is 190g.
