I wouldn't worry so much about what rims your pick out. Seriously, most double wall, machined side-wall rims will be fine. What you need to worry more about is a quality build. Proper spoke tension and lacing is more important. Now getting back to your real question....
The Delgado's are sweet rims. I've built up a couple pairs of them. The thing with them is that they are wide. And their heavy. But strong as hell! I like them, would race them and train on them.
I personally like the open pro's. They're just a shade over 400 grams each, and are double eyeyleted. They work for most people. Superheavy weights may want to stay away from them but again with a proper build, (higher tension, 130kgf on Db's) they would be fine. I run them on my single speed cross bike, beat the hell out of them and they stay true as can be.
Now here is another thing to consider......If you have to do a wheel change with someone else on the course, the Delgados are really wide so if you grab someone's open pro, they will be much narrower and you may not end up with good braking. Inline barrel adjusters can handle that problem though. I have them for my brakes and it's saved my butt more than once. Especially the real narrow rim to a wide rim. This way you can loosen the cable and still have brakes!
