It has been a while since I have been to Breckenridge, however, from what I remember of the terrain and trails it is 'rocky'. I am not sure that I would like to get caught out on punctures there - this will matter whether you are going into true back-country or finding your way around on resort cycle paths.
My recommendation is for the Specialized 'lightweight' 'Armadillo' tyres 'Captain Elite' - dual compound, nice and nobbly, good TPI casing, foldable - the wishlist boxes get ticked for where you are riding and what you plan to be doing (that'll mean no mud, then).
For the front you can put the 2.2" and on the back the 2.0", and in 29-er.
Anyway, I am quite envious - I wish I had got my act together and had the dream to head off to Colorado for cycling this summer! Enjoy, I am sure you will.
