I just gotta jump in. My Ultimate Seat is now the Mid Rider. Long story short, a long 600 mile ride on RT factory seat found me unable to walk because the seat really made me hurt. I immediately ordered the Ultimate Seat. Not understanding how to properly ride the Spyder, I thought the Tall Boy was the way to go. Short 1 1/2 inch difference but it made a difference in how you handled the Spyder. Russel at Ultimate Seats set me straight on how to ride. He said your elbows should be bent because that is how you maneuver the bike. But then, I'm 5'8" so if you're taller, the Tall Boy would be right. Let Russel decide for you. Their exchange policy is most excellent. I swapped the Tall Boy for the Mid Rider. It made a difference in handling. But to the seat itself, I now have about 2,000 miles on long trips under my butt and never even once for even one second has my butt felt anything other than a comfortable spot to sit. I feel guilty that I'm enjoying sitting on the seat. Combined with the Seal Floorboards I installed, I don't feel as if I'm on a 'motorcycle', but feel more like sitting on a comfortable chair at home. Do keep it dry though. Someone else mentioned and it's important. The Ultimate Seat Ride On seat cover costs an extra $10 but it is insurance against the foam getting wet. Fits kinda sloppy but it works. Did I mention I absolutely LOVE my Ultimate Seat. Whatever the cost, it is worth every damned cent. Many times over.
