too bad, it happens.
IME, comfort has pretty much to do with things that touch me, like handbars/grips, saddles, and shoes/pedals, and the shock absorbing effect of tires and their PSI, not frames. hang the right, saddle, pedals and handlebars at the right distances from one another and the comfort will be there for me. you might try experimenting a bit if you heart is still in it.
of course weight is weight is weight...
