Right now for the big six my best guess would be these are the mins to possibly get called...

Fighters about 2K (almost all of which is TPIC).

Mobility 4-5K (1K+ TPIC).

MPRA is more tactical than mobility, so I'd guess somewhere in the middle, 3-4K?

I'd apply everywhere you want to be, hope for the best but plan for the regionals.

Second tier/LCC is also an option, better life and pay out of the gate, and if you get stuck it's still better than a real job in the long run. Downside is upgrade would take longer than at a regional... fast upgrade at a regional (if you're still there for some reason) will put the 121 TPIC icing on your resume cake.
