I was recently in this situation and had to make a decision...I was flying both a King Air and a Caravan part time for two different operators...Had roughly 300 multi, and 500 turbine. The Caravan operator made me an offer for full time, and around the same time, a piston multi operator also made an offer for full time.

The way I see it, what good is thousands of hours of single engine turbine, if you don't have the minimum multi to even submit your resume to that dream job that requires 1,000 multi to be looked at.

It was a hard decision, but what really pushed me towards the piston multi was something a friend of mine at the caravan operator said to me, and to paraphrase, "I have 40 hours of multi engine time...Unless someone wants to take a chance on my low multi, i'm stuck here". This is coming from a Caravan/PC-12 PIC.

My goal is to remain 91/135, and my hope is to reach 1000 multi within a year. I don't have a lot of turbine time, but between the two King Air Flight Safety's (Initial/Recurrent), and the time logged, i'm hoping it's enough to show someone I understand how a turbine engine works, and how to operate it.

Depending on the economy, the "filler" job you take today, may not be something you can leave in 12 months for the next best gig. You very well may end up doing 1-2 years with them before you can move on.....Certainly keep that in mind.
