After doing more research and question-asking, I was referred to this website: http://www.cobbcycling.com/

The V-flow Max ALMOST looks like it could do the trick. I want to compare its dimensions to the Adamo (and I've asked my LBS owner if he could possibly get one in for me to test ride), but it MIGHT work out. I'm thinking about trying one of the longer/narrower Adamo models (Podium, I think) as well.

I have the feeling this is a leg-length discrepancy thing, and I'm trying to find a way to sort it out without having to go back to soft tissue pain and tears.
