Of the two bikes, I would pick the Norco. Solid, reliable, good bang for the buck.
If I may make a suggestion, take a look at the Cannondale Gemini 600, or 900. Both are in the 35 pound range (for a 7-7), are wonderful going up or downhill, and have an excellent price point ($1799USD, and $2299USD MSRP). I recently purchased a 900 over the Norco and RM, and couldn't be happier with it.
