There were 4 Endeavor FOs in my class. 7 year, 6.5, 3, 3. That's saying something. It's a tough call. You have to look at your current prospects and decide if it's better than a 1.5 (worst case) year or so upgrade. You have to do what's right for you.

I was the least experienced guy in my class with 1 year at xjt and 600 turbine.
