I'm in the same weight category, I'd also vote for Montague. I've taken a Montague CX with me on several overseas trips. My last was a 1000km+ loaded touring ride along the Queensland coast in Australia (I installed a rear rack from tubus), followed by a 3000km bus trip to return from Cairns to Darwin.

The frame has proven to be pretty strong (and sufficiently stiff for comfort). The bike has hardly any original components left though. Changed from 7 to 8 gears, replaced my rear wheel with an extra strong custom built one (spokes kept breaking ; now using a tandem hub, an Atomlab Pimp rim and DT Swiss Alpine III spokes). Had a rear dropout bent by an airline - they had to be replaced (I'm using a bag for transportation, that way one-way transfers are no problem - I'd now take off the rear derailleur prior to air transportation) ; my front rim was worn out by braking so replaced the front wheel as well,....

My last change were the Bowden cables to the rear derailleur ; they kept getting clogged up by dust so had them replaced by a less segmented type,...

If strength and/or compact transportation are important, I'd choose the CX over the other models (more compact (threaded mount front fork is more compact after stem is removed), quite strong steel rear triangle, fixed steel fork, ...)
