That's all entirely up to you...what do you want out of life?

Lifestyle-wise, there's a lot more to do in the front range than in DTW. As a street CA you'll probably be on reserve in DTW for a LONG time. If your main form of recreation is video games, it shouldn't matter. Otherwise...

QOL...obviously you'll have more time off and schedule control as an FO rather than a CA at any airline (not to mention a street CA).

Money...how bad do you need it?

Career Goals...this is the toughy. Obviously you need the PIC to progress, but PIC alone won't do it. Oil is up, hiring is down at the majors, UAL is throwing the "F" word around again, and we just started the five-year "window-of-pain" for age 65. Do you have a REALLY good connection at a good major (that will be hiring for several more years)? If so, it might be worth jumping on the PIC at all costs. Otherwise...

Also what are the growth opportunities at Lynx? If they're still expanding, an FO job there might turn into a CA job real quick, and without a bunch of senior FO's on top of you. That would be a huge factor for me, and I would do some research. Don't just take for granted what somebody on the internet or a recruiter says, look at SEC filings and quarterly reports...hard orders for airplanes (as opposed to options) would be a good sign.
