Following this thread, please continue to post updates. I'm a large new rider also, 6'1" and 300 area.
I'm riding a Cypress DX and every single day it's getting better.. But I'm with you on the ass and especially nutsack pain. the nose of the saddle is pissing me off and rather uncomfortable, regardless of which seat I've tried. I didn't know noseless saddles existed, I'd like to hear more about that
