Think verrry carefully about coming to the regionals. What will 5000hrs SIC RJ time get you that you wont have now? The quick upgrades at regionals are in the distant past, and the future isnt looking too bright as well. Quality of life will plummet down the tubes compared to what you have now. Like fjetter said, try to jump to the left seat at your current gig, or wait it out until you can. That PIC turbine will mean a lot more than SIC RJ.
