Hi! Depends on your location.
If it’s state side I would guess you’ll be busy. Bigger bizjet market out there therefore plenty of work but if it’s the uk you should have a half decent work/life balance.
remain current on whatever type you’re on and keep that in your back pocket just in case and if all goes well with the falcon training aim to get trained up on as many types as possible to make yourself more in demand.
as for an SFI lifestyle...like any job with a fixed salary it all depends on the contract they’ve offered. If you were to go freelance then the world is your oyster! You just need experience and some good type ratings under your belt and shop around for work that works for you.
