2.5 FO here..
With a line anywhere between 14-18 days off a month on average, bidding two and three day trips...sometimes trips are back to pack for 6 day stretches but it's kinda rare. Overall no complaints... I feel like I'm off more than my friends at other companies. I got a line after my first couple months and greatly improved QOL.
With reserve expect 12 days off...after a few months you should be able to hold weekends off at least. When I bid reserve about a year ago on purpose I was hardly used (went 30 days without a call), but I think those days are over from what I'm hearing.
PM if you have any more questions.
