The Mustng Fastback Tripper is a huge improvement over the OEM. I like sitting a little lower & it fits me well at 6', 32" inseam & 270lbs. I think I'll try the RDL next since I hear such good things about it. I also use the beads when it's real hot & an Air Cushion on long rides. Alternate them as needed. Sure ready for all this rain to quit.
