I currently ride an HED C2 Belgium (23mm wide, 24mm deep) 24 spoke rear wheel. At 155 lbs, the wheel has been very solid and hasn't required any truing since the initial build (about 3000 miles ago).
I'm thinking of building a really light set of "race day only" clinchers around either a Kinlin XR-200 (19mm wide, 22mm deep) or a Kinlin XR-19W (20mm wide, 21mm deep). The 19W is a stiffer rim from what I've read and I think I'd be able to get away with a 24 spoke rear. Given the success I've had with 2x on both sides, I'm tempted to go that route, but am also intrigued by half radial and triplet lacing. All of the races I'm doing are uphill time trials, so they'll (mostly) see steady power output on good roads.
I've read a lot of good things about triplet, but only 8 NDS spokes sounds a bit iffy.
