Hmm.
1. The president of the club I was with in CA had a similar set up after he got hit by car, I agree it would be a lot of re-adjusting. I've done a endo like Oakleaf did
2. Surgey is well... Surgery. There's always a chance it won't work, so getting a second opinion is a good idea.
3. Bents - I love mine, but I'm not sure they would work. Have you gone to Wheelworks in Belmont? They are a Bachetta Dealer. I'm sure they'd let you take a Giro20 for a spin. Still kick myself for getting rid of mine. It's a good bent and should set you back about $1600. Not sure if they are any other dealers in Boston
