Did this myself, with similar stats. I tell folks the only thing the jobs have in common is that they both involve flight. Miss the relative stability and schedule of the airlines. Might be headed to Moscow tonight, I just have really no idea. 20 hour days are totally normal. Just my take, but if you have seniority where you are now, you will probably take a large hit on lifetstyle/sked and pay for quite a while. Good luck!
