This about the lightest aero aluminum rim you can get.

I have a set of these on my roadbike and they built up quite nicely too. They have a good rep in the roadie forum.
The CXP33's aren't aero by a long shot. The section is 23mm. The deep v's are 30mm. Some other options include
Alex DA28 - 27mm profile
Campy Eurus - 30mm
Some other rims that might be hard to find.
Mavic CXP14
Mavic CXP10
Gippieme Tecno 416
Anything with a higher section than 30mm is going to weigh more than supertanker without going carbon. If you are going carbon, there are a LOT of options.
P.S THose niobiums are 30mm - same as deep v.
