@asdf123: When I built my C59 I chose to go with Look Keo Blade Ti (16N) for probably the same reason you want to go with them right now. I wanted an all "euro" build. I've always been using Dura-Ace pedals up until this point, but really wanted to try the looks and thought they just looked really sweet. Well, they do and they are fine pedals, but after only about 100 miles on the Blades, I just decided that for me the Dura Ace pedals worked better. You can walk around on the cleats easier, which is important for me, maybe not for you. Also, the Looks have two cleats, one designed to be easier to walk in which have little rubber tabs on them and the other are just hard plastic which are like walking on a skating rink. I tried both. The "walking cleats" were better for walking in but no so great for riding in as the rubber pads tended to stick a bit, an unacceptable compromise to me. So I tried the standard (non rubber tipped) cleats which were much better while actually riding etc. but useless when off the bike. The big draw of the Blades was 1) the look, and 2) the weight (very light at about 185g vs about 250g for the carbon dura ace). However, overall I like the Dura Ace more and went back to them, and stick with them on any road bikes I have. They seem bomb proof, I've never had an issue with them, and they are very well sealed with great bearings. And during both riding and walking I feel they are as good as it gets with a road pedal.
I still have those Look Ti Blade pedals, I really need to have a garage sale
