PBS by far. Bonus structures are mostly tied to the PBS system.

3 strategies:
1. Bid medium amount of days like 15, then offer to extend for 2xOT if it's available.
2. Bid max days possible, you'll likely see 8 day rotations, and you can waive some of the days off "yellow lines" and go from there.
3. Watch for the "build custom long schedules" email and offer to go nuts on the road. They are custom built long-stretches for the single folks among us lol

I bid for 12-14 days; I have gotten 17-20 days this quarter no matter what I bid. A little burned out, but not the end of the world. I'm also on track for like 140k if this 1st quarter 2023 keeps up (I won't let it) but you get the idea. Enjoy.
