Anybody want to compare a top of the line Klein to some of the other high end race frames?

I've ridden Trek 5.9 series and liked them a lot. I've liked the 'Italian' frame geometry of my three DeRosas, even though the King was relaxed, while the Dual is very twitchy--different feels, but both excellent rides..I like the conservative geometry("on rails" downhill and through the corners) of my current ride, a Look 585. I didn't like the fit of Colnago(too short on top) and I didn't like the feel of the one Time I rode breifly. Had an Orca, but thought that was a bit soft and vague cornering. Had a Cannondale Caad 7 but it was too buzzy, too "tinny" and I hated all the clicking and wierd bottom bracket/crankset noises, as well as not being able to use an aftermarket setup there.

I'm a bigger guy, about 6'1" and 165, ride lots of climbs, race often in masters category and do about 13k miles a year. I usually have two bikes built at any one time, right now, a Look (as mentioned) and a DeRosa Dual, which is a carbon front back/aluminum main triangle that is my climbing and sometimes crit. bike. I want to replace that with something due to some crash damage. I have a big friend I train with who rides a Klein. Amazing climber for his size but somewhat odd to try to get info out of.. I see them at crits, also, ridden quite well at times...

anybody want to give an opinion of the top-end high performance Kleins? I would probably go for a used one off Ebay..
