I have been using "Control Tech Race" skewers (http://www.controltechbikes.com/english ... kewers.php

They have worked flawlessly. I have ridden that bike quite hard, hitting rocks big enough to give me a few flat spots on the rims. They have never come loose. They weigh just under 50 grams.
Last year I bought another set for my first road bike, a Serotta Ottrott with Mavic R-Sys SL wheels. Again they have been functioning perfectly. Two months ago, I replaced my road bike with a Storck Fascenario, with Reynolds 32 carbon tubular wheels on Tune hubs (front: Mig 70; rear: Mag 180). The spacing on the rear wheel is slightly larger with about 3 mm of the nut threads exposed, so I am going to replace them with the 135 mm rear skewer (spec'ed for MTB use) and go with the "Control Tech Race Light" skewers (http://www.controltechbikes.com/english ... kewers.php
