I would put both Boise and Oregon at Tier 3, and would not elevate anyone to Tier 2 to replace them. I can't argue much about UL and App at Tier 4, but I might put both GaSo and CC in Tier 5; GaSo because they have fallen off the last two or three years and CC because so far we don't know whether they are a one-hit wonder or not. Liberty in Tier 5 is also questionable; I might have them in Tier 4.
