Go Go GO
I think you should do whatever you want to do, i.e. if you want to fly for the airlines peace out and go to the regionals. Commuting, prior to contrary belief, is not that bad, nor is fighting the low pay for one or two years. Being on reserve sucks a little but you'll get through it pretty quick. Once you upgrade things start to go uphill pretty fast from there paywise and seniority wise. Do it.
