Aztec, yes, you could theoretically hold CRW if you wanted it. I got it in training but am bidding out so there will be at least 1 vacancy there (hopefully) if you get in and want to go there. Obviously the sooner you get in, the better seniority you will have and the more likely it is you can hold Charlie West. Keep in mind it is a Saab base, so if you get the Q you won't get it. I've only seen 1 or 2 reserve lines, it seems to vary month-to-month as far as I can tell. Trips there are mostly day trips but there are a few overnights thrown in. I've heard, like many others have, that the outstations are closing so who knows how much longer CRW will be a base.
Classes do start on Tuesdays, not entirely sure why, but that is when they seem to be starting.
