If you want to go with the airlines when you get out it would be a smart move to go to the traning command for your final flying tour to get more than enough hours TT for the airlines and the 1500 ATP requirement (assuming that the request for the 750 hrs military time is not passed).
Going to the the RAG or a C-12/35 assignment might be risky. Lots of hours one month and few the next. If the training command is what it use to be (Bunk or FlyBoyd could chime in here), then you would have no problem making the totals.
