In reply to Mike Shamash: The weather will almost certainly be excellent.
Some issues - it can be hard to find things in the flatirons. Finding stuff in Boulder Canyon or Eldo is easy in comparism. I haven't been there to climb for a long time, but there wasn't very much lower grade sport close to town last time I visited. Grading ran quite hard on the trad routes, but I found some of the sport grading very soft, and some of those routes were not of great quality.
