OK, so today I took a 175 mile ride with the new seat. In short it is an omprovement but not big. The seat is wider so you move around a little more. I had boxer short on under jeans and they are VERY uncomfortable as one of the seams went under me and the seat. For long ride like this I normally wear LD boxer's, they make a big difference. My GF thinks the new seat is a little resctrictive since the passenger seat part ramps up at the front than the stock seat. Also, the cover is a nice carbon fiber look and it is easier to slide front to back than the stock seat cover.
Anyway, so was the seat worth the $280, kinda when you consider that a custom seat is over two times that amount.
Good Luck guys!
