If you can take a week off and do a ride in appt at Russell, where they make the seat that day and can adjust it to your exact specifications. Ultimate only has a 14 day return, you pay shipping both ways, there no way you can tell if that seat is going to fit you in 2 weeks, it will never reach full compression in that short of time. Even with my Russell it took about a 1000 miles before I felt even the slightest compression. I mailed mine away to Russell and with the ht/weight inseam, pictures etc. you give them they have it down to a science. Humble opinion.
