I'm a Russell fan. I've had them on three bikes, now. For me they are a bit of a hassle when stopping and stopped (I am 5'6"). I have to slide up on the seat at stops in order to get a toe down. I still have the oem seat and use it for the 70 mile commute and local use.
If I'm going to be on the bike for several hours, I switch to the Russell. Oddly enough, the Russell isn't that comfortable, as in plush. It feels firm and unforgiving. Still, I can sit on it all day with no butt discomfort. I've never been on one of the thicker Russell's made for more normal sized people. I imagine they are a more plush.
BTW, I bought this seat from a fellow on Craig's List for $200. Remarkably, he happened to be the same height and weight as me.
He had the seat made and had only ridden it for about 100 miles. He didn't like it and put it on Craig's List.
