Fellows and ladies

Mountain biking in general is an issue I have a very limited knowledge. I come from a road background, but the traffic is pushing me away from the road into the dirt.

I have the possibility to buy at a low price a set of Bontrager rims for my xc bicycle. The front rim 24 holes and the rear 28. I am a very light fellow, 54 kg and I intend to make 200 km of xc per week, wheels on the ground on a bicycle with V- brakes. So, what in your opinion is the best rim for my needs: Bontrager Select or Bontrager Race, taking into consideration weight and durability?
