Alright, so I test rode a 595 today. First, the LBS was kind enough to cut the seatpost so that the saddle height was 15mm too high. Nice. And then they put on a 130mm stem. That's mostly the bad news. Pedaling seated was a, uhm, challenge at best. I spent most of the seated time sitting on the rivet, with my legs hitting full extension at the bottom of my stroke.
I didn't have my wheels, and they had Kyrium ES's on the bike, with Hutchinson tires inflated to my usual riding pressure. With that said, the bike was more compliant over bumpy stuff than my Moots. The difference was subtle but noticeable. I can't however say that the wheels and tires didn't have something to do with that.
I wanted to test the bike on a climb, so I found one of my local hills that has a 200 yard section of 25% grade. The Look did seem to climb a bit better than the Moots. Maybe more than a bit. It went up quite well.
Given the LBS setup issues, climbing seated was not an option.
Over all, the bike displayed a ride character that had none of the dead feeling that people complain about with CF bikes. If I'd been blindfolded, I wouldn't have been able to tell it apart from any metal bike.
A monsoon storm cut short the climbing--I didn't want to [censored] on the LBS by riding the bike in a torrential downpour--so while waiting in a dry spot for the rain to stop, I looked closely at the frame. The frame was an XL, and it is certainly the size for me. I think with the seat mast cut to the right height and a 120mm stem, I'd be right in my sweet spot on this frame. And as a bonus, I'd have quite a bit more room to alter my position than I do on my Moots.
So, I think buyin' a black Look 595 is definitely in my future. FWIW, the frame I rode today was white, and its finish was beyond reproach. In fact, the finish was about as perfect as a finish can get.
I'll be riding a Parlee Z4 in the next week or two to see how that works, but at least on paper, the Look is the better match. We'll see what the road says in a few weeks.
