The deeper dish wheels do make a difference when riding fast even if you are not "off the front". I have been using my Williams Carbon 58's for the past month in races and I can tell a difference even though I don't have a PT. These image links show me racing and going through a 40 mph turn. The downhill continued onto a slight downhill flat and the field would split up some on the crit's decent. We would then be riding in single file for about 1/4 mile, while the riders would frantically work to get back in the leaders draft, before we started back up the hill for the next lap. I loved the wheels on the decent and during the "catch up". The 1.3 mile course was basically 2/3rds downhill, with 4 turns, then back up hill to do it again. My son purchased the same wheels as Herme's has last year and had zero issues with them and is planning to use them during cross season this year. This past spring we both purchased the 58's and got a "small group discount".
Even if the wheels didn't help make me faster the "cool factor" from the look and, even more so from, the sound the wheels and bike makes when riding and shifting are worth every cent to this old racing dinosaur.
