New Rival Crankset with an old drivetrain? other options?

[d_douglas]

I am looking for a double crankset to use with my vintage SRAM XO 9spd drivetrain. I think the SRAM stuff is beautiful and it works perfectly. I used a Raceface 32/22 on it before and it was flawless, but I have repurposed that crankset, and need another one for another bike. I would like it to be somewhere around a 43-30 or thereabouts (I am flexible).

Would a new SRAM 43-30 crankset work with 9spd SRAM MTB parts? Are the rings too narrow or the tooth profile too modern?

What other options are there for a setup that will work perfectly with this 9spd stuff? I could find another Raceface triple crank and just drop the tiny ring again. I am trying to do this cheaply. I know White Industries would do the trick, but I am not in that market....
