Well I'm one of the very few people who've ridden a Romax on this forum, so I'll put my 2 cents in:
I'm 6'0", with a 33 or so inseam, and generally ride a 58-59cm road bike. I ride a 56cm 07 Brodie Romax and it's perfect. I ordered a 58cm Romax frame to build up, but they sent a Romax bTeam Scandium frame in 58 instead. Luckily, there was a 56cm Ronin in the same order that I was able to ride and figure out that it fit perfectly. The 56cm Ronin/Romax actually has less standover than a 56cm Fuji Cross Pro (which is supposedly the same as the Motobecanes geometry wise). One guy who bought a Ronin in the shop went from a 61cm Bianchi San Jose to a 60cm Brodie Ronin. The Ronin was bigger, which worked out because the San Jose was a smidge small. My LBS owner usually rides a 56cm Fuji Cross Pro, and he's building up a 54cm Romax like mine.
So, my vote is to size down. And between the Brodie and the Jake, the Brodie has a sloping top tube which I liked, and at least the 07's had discs and rackmounts, which was the clincher for me. If you want to see pics of mine built up, click the link in my sig. I've got over 1000 miles commuting/group rides on it and it's just about perfect.
