Dash,
I think there are lots of SLC refugees are in the same boat as you. I am thinking of bidding back to SLC on 737 or 320 reserve because as you've mentioned, the amount of reserve in MSPM88 is just plain unfathomable!
I think most of us that got MDed out of SLCM88 are getting very frustrated because we didn't have a choice to time our arrival in this new base, and the trips just aren't as commutable as SLC used to have. I hope there's a way to tell when they'll actually increase the number of lines, but as fall/winter schedules befall us, it could only mean at least 6 more months of reserve for us all...
