That is AWESOME! I was going to suggest listening to the JRE episode 1109 with no other than... Matthew Walker as the guest. It's one of the very few JRE podcasts that I listened to and then saved because it was so good. IMO, unless you can get proper sleep a WB is going to take years and years off the end of your life. I was on Delta's 7er category which is split between 757 and 767s with both international and domestic routes. I felt like a zombie during my international trips and after TOE I never bid another international trip. No desire to ever go back to a WB unless it's sitting RES and rarely flying. I'll work my butt off during normal business hours before I go back to the luxurious international lifestyle of slowly killing myself with high calorie low nutritional value meals and decimated sleep cycles.

That said, to address the OP your question is very dependent upon company, work rules, base, and category. I'm a very junior NB captain but because of those variables I listed, I've only blocked about 300 hours in the last year. I live in base so while SC still sucks, I don't have to commute in for it. My category just happens to have a lot of pilots who are happy to fly their butts off for straight pay, so lots of trips that look like they have my name on them get picked up by line holders depending on the month and day of the week. I also actively manage my schedule to minimize my availability to CS and maximize the chances that my RES days fall during periods of time where it's more likely for somebody to pick up open time.
