ASA is likely your best bet. HOWEVER, most new hires are going to the CRJ700 where the reserve will run you at least 1 year. The CRJ200 will give you better QOL if you are senior enough in you class to get it. If so, expect to be on reserve for 2-3 months. After that, you will rack up about 80 hours of block time per month. You will probably have an easier commute from MIA to ATL. Good luck!
