I have one of the new Petzl harnesses (the one with adj. leg loops). I like it very much, climb single pitch trad and sport without any problems. It doesn't have a haul loop, but you can get one sewn on pretty easy. The only really problems is I wore through the webbing on the legs loops at the buckle from doing OW. It isn't the best harness for really long routes, so I now own a Mistly Mtn. big wall harness for multi pitch stuff.
