Good luck with the build. The DRC rims might be interesting if I can get them sent here.
The more I read this evening, the more it says that the rim is where you want to lose weight rather than the hub - which makes sense as it's rotating mass. Therefore Tune hubs seem like vanity/dick measuring to get wheels down to a stupidly low weight without huge additional benefits.
Hopefully disc wheels on road bikes will make a difference there - less material needed in rims.
A DT build or factory wheels are starting to look like the sensible option. I'm leaning towards handbuilt for the ease of sourcing parts etc.

What tyres and tubes are you going to use?

For weight weenie hubs, they are very durable. That's worth a premium for.

Keep reading, you'll eventually stop believing that.
The important question you should answer, which will lead you to making the right choice, is do you want to weigh your bike, or do you want to ride it? If you want to ride it, and especially if you want to ride it further/faster/higher, then pick wheels which are reliable, have low aerodynamic drag and mount your chosen tyres in a way which enhances ride and handling while reducing rolling resistance. Once you've got all that sorted, you'll find out what your wheels weigh. Picking an arbitrary target weight and trying to hit it at the expense of other things gets you bragging rights on the weightweenie forum, but you end up with a slower bike which is less fun to ride.

There's also a more current debunking by one of the Straylian Aerocoach chaps, but trying to find anything on TTF is hard work.

No idea if they'd explode on the first ride but DRC KTC 380's plus some chinese hubs and cx rays, would come in at 1252g for the wheelset, be wide and alu, and only cost 250 before theyre built (I'm planning on building this wheelset for myself). Tune Mig/Mag's would get that down further to about 1200g, but would more than double the cost of the whole wheelset.
