Need some advice, which cranks of these two? note I already have both!

So basically I've acquired me a TREK Fuel ex 9 2007 frame. I bought two sets of cranks, a pair of shimano xtr m970 (run in single speed) and a pair of 83mm Raceface Atlas cranks. I'm just gonna run single speed, which one should I put on? Figured I'd ask you guys! With the raceface I'll need some adapters of some kind as my bb is 68mm. Thanks!

Of the 2, would go for the XTR (this is on the basis you already have it setup as a singlespeed/ring) Using an 83mm BB crank will give you issues with the chainline, if you can even get it to fit your frame (see this thread for issues and possible solutions http://www.bikeforums.net/showthread...n-73mm-68mm-bb ) with the M970, the BCD is standard 64mm/104mm, but is offset, so you may need to use spacers to correct the chainline.
