Glad nobody was crossing below them, Armada. Flying NW bound near Co springs like that can leave you stuck in the descending side of a rockies wave for a while. Bad deal without much excess performance to play with. My friends who fly Challengers have commented that the CF-34s really peter out above FL370. It's no Gulfstream or Lear and the wave around there can get pretty strong. Glad things worked out OK.
Best,
