custom wheel build--which rims?

I'm building a disc cross bike to be my commuter/bad weather bike. I haven't purchased them yet but I'm going with xt 6-bolt hubs. I'm not sure about the rims. I've got a pair of mavic ma40s hanging in the garage. Yes they're vintage and they're 36h, but I had some on my first road bike and they lasted 18 years w/o any problems. Reading the other posts, many have said go with open4cd which is a successor to the ma40. So my question is this...use what I have or buy something else? I'll probably use 32-35mm width tires. I'm a small rider, about 5-7 130lbs, so I'm generally easy on equipment. . Weight is a moderate consideration and $ are probably more important these days.

Any obvious selections I'm overlooking? Or just personal preferences you have...

Dude/Dudette,
Use the rims you have. At 130lbs your are a very light rider. With 36 hole in 3 cross lacing they will be more than strong enough for you.

Velocity Synergy front, Synergy O/C rear.

If you want to save 140 grams, use Aerohead and Aerohead O/C instead.

I would just use what you have. Even if modern braking surfaces are better or whatever, that won;t matter for your disc build.

I would also vote for the rims you already have. Save some money and put it towards something more exciting than rims like your first cross race or a big charity ride. The ones you have should be plenty strong and reasonably light, especially for a commuter/bad weather bike.
