Wisconsin is pretty competitive. If you know someone there, then you should wait for an interview with them. If you don't know someone there, then don't base your decision on whether you want to "wait" for Wisconsin or not. It could be a very long wait...

As for Pinnacle, I think people give it more crap than they should. Talk to one of the pilots that work there. I've got two friends that work there that say the same thing about it - "Not that bad if you don't commute"

There is more apparent instability with Pinnacle than there is Wisconsin because of who they fly for, but you could hold a line with Pinnacle MUCH quicker, especially if you're willing to live in Detroit.

I say if they give you a job, then take it. Who's looking much better right now anyways?
