Got my hands on the Pruitt. Got my hands on 2 used saddles from my LBS. And... it looks like I may have a winning combo.

I did the math to get an idea of what sort of bike geometry I ought to be on. I'm 5'6", with a 29" inseam, and a wingspan of iirc about 5'8". This means I should be on a men's frame (which I am) and I logically shouldn't need the handlebars higher, since they're level with the seat. So, I'm now doing stretches for my back and leg muscles to get more flexibility. I'm also working in shoulder and neck rolls. I have better wrist position, and I'm not putting as much weight on my arms.

The two saddles were chosen to be as T shaped as I could get, with the firmest seats I could get, and narrow noses. One has a shorter nose than the other, so I could play around with just how long a nose I need. I plonked one of the saddles on my bike (turns out it's the short nose one). A 6 mile ride in shorts that previously had left me in agony left me with no saddle sores and no agony. Well that and a conviction that I need to push my speed more to continue building my core *g*. I'm now comfy enough that I feel like I can push for more distance and not hurt myself. I can have comfy wrists, a comfy butt and air!
