I got a high-speed (continuous duty) line this month, my third bid cycle and my 4th month flying. Not sure I'll be able to hold it consistently, we'll see.
Time to a regular line, who knows?
Continuous duty trips aren't for everyone (check in around 2200, fly out, 4-6 hours in a hotel, fly back, released), but I like it because I can commute home more easily (16 nights at home this month) and the company picks up the hotel room in Cincy between pairings if you want to get rid of the crash pad.
