As a former Silver pilot I'll echo what Chris said... Don't walk run from Silver. You won't realize how terrible it is there until you're gone. Look around your fellow captains and FO's there and see how many are leaving for a Major or LCC. Very very few where as my time at Horizon and Skywest I've met more FO's moving on to greener pastures than Captains at Silver. Commuting sucks but living in a Silver base is worse than commuting to a "better" regional. As far as Mesa... Well you'll be making the same as you did at Silver only difference is the equipment you fly.
