Thanks for the replies so far.
The ratings will not cost me anything. The company will pay and there is no bond.
I already work for the company who have the Chieftain (I've been flying a Baron and a C206 for them), and the other company with the Caravan is my friends dads company.
I know the Caravan wins hands down on reliability, but if I fly the Caravan it will be two crew for insurance purposes. I'll get plenty on command time but 2 crew on a slow single....come on!
Salaries will be much to same, so nothing to sway me there.
My main issue is what looks best on my CV/logbook when I return to UK for a job.
Keep the replies coming
