WRT timeline, I had 10 months between my FC1 and OTS. 9 months from AFRC board OK to OTS. Once you in process in person with the 340th, you should be close.
If you’ve been picked up by a 135 unit, you’ll fly the T1. The only way guard/reserve go 38s is if they’re going to a fighter unit. Especially reserves, they have very very limited 38 allocation.
