Kordon, I recently purchased a LOOK 585. Rather than replicate my setup on my old bike, the fitter (a great one btw) setup the LOOK with the bars about even with the saddle (3cm of spacers) with the intent to remove spacers until we found the best position. With the variety of sizes, I believe you can find a setup that will work for your back.
If a LOOK is what you want, go for it. I originally was looking at bikes from other manufacturers and tested rode the LOOK to kill some time while they setup a Colnago. It spoke to me (in French of course so it may have said “get you old ***** off of me you fool”).
