first off hope u have a full recovery sure glad you survived that crash.

anyway the first thing u should consider is to get a proper bike fit done before you part with your hard earned cash.a pro bike fit will tell you exactly your frame size your saddle height your reach your bar width your correct cranks basically everything .if it were me i would be going with a TI frame last forever .i don't like disc brakes no need for them and they only add weight to the bike IMHO.take a look at the Thorn club tour or thorn sherpa cracking touring bike's or just buy frameset and build it yourself.best of luck with whatever u choose oh the Marin would be my pick of the three u listed but as i said Thorn is well worth looking at.
