I've got the one piece dual tour seat (maybe gel?) and the rider backrest... not a bad setup, but my fat arse is about 230 lb, so I'd like to end up with a stiffer seat that's got a larger, flatter section in it. As is, this seat puts a lot of pressure on my sciatic nerves and numbs my legs out after a couple hundred miles. Not that I'm particularly cough well-endowed cough, but I have to be careful that my jewels don't get smashed up front either. Seat is not an ideal shape for the male anatomy...
