Questions for Pinnacle guys

I am currently just starting to CFI and am looking at the next step. The short version is that I am looking for somewhere to get a bit of experience for a year or two and then going to another company. I know that this so called horizontal move is considered bad but I would much rather get some 121 experience then just sit for ever as a CFI waiting to get some multi time.

My questions are
What is the call out for reserve, 90 min, 120min, ect.
What are my chances of getting DTW as a base? I am stuck in Michigan for about a year and would not like to commute if possible.
How long is reserve for DTW?
Any tips for experience and studying in order to be competitive and successful?

QOL and pay are not too big of a deal, not really looking for a carrier here just for a stepping stone to other things. Any advice as to another way always appreciated also.

Any help would be appreciated.

Thanks
