I did PM reserve when I commuted. Actually, it can really work in your favor, particularly the way Scheduling splits up and puts trips together.

Often times as a PM reserve, you'll start in the PM, but you'll end up flying mid-morning day 2, 3 and 4 if you're on a 4-day block. Often times, you'll cover flying out of your own base and then they'll deadhead you back to your own base. Prior to that deadhead, you can ask them to release you from DH so you could commute home. I think they only didn't release me once as I only had that DH that day. When I returned to base, I asked them again, and they released me. In 3 months I commuted to reserve, I think I only spent 3 nights in base on my own dime.
