Excellent...thanks both...that was helpful, so truly customized, an interesting proposition! I suppose then if I ever wear out the Corbin, I'll try a RDL...sounds like it might be so comfortable, I'd never stop riding...maybe that's the ticket for doing an Iron Butt or Saddle Sore 1000 run!
The only thing I can see that I don't really like is the shape...those wings, which I'm sure add to the comfort just don't look great, but that's just my preference.
