Just wanted to recommend the Mustang Tripper solo seat. Just put it on my Nightster. Other than it being a biatch to get on, it's nice. I'm 6' so it does two extra things, in addition to the expected of making the bike more comfortable to ride and improving the rear-end harshness. (1) It lifts me up about an inch and (2) lets me sit back farther because it doesn't come up so dang much in the back. The downside of it not coming up as much is that you don't get that butt-slip stoppage as much as the stock seat, but the padding and the fact that you won't slip anyway makes up for it. I hear the Corbin seat is nice too... but I didn't like the leather texture.
