One other thing that may be a con. New aircraft in the fleet often have teething problems. MX isn't familiar with them just yet and you may be cancelling more flights than you'd like to.

Does Colgan have a seatlock? If not you could always bid back to the Saab down the road if you could stick it out commuting for a while.

If it were me, I'd go for quality of life first. The pay's all the same (it sucks) do what puts the least amount of stress on you and your family.
