If you want schedule flexibility there is only one choice at this point. PSA has by far and away the best schedule flexibility of any regional airline. 5 days off in a row is no problem. Want 2 separate stretches of 5 days off? No problem. Meet the SAP. It has flaws but is still an incredibly powerful QoL tool.
The only caveat would be that you must be off reserve to enjoy this benefit. Someone posts our reserve time in table form every month in the PSA info thread. Check that table for current times to see if it would be acceptable. I would expect those reserve times to come down a bit but I would use that table as a "worst case scenario".
While you are on reserve you should still be able to get your stretch of 5 off in a row but there would be significantly less choices as to when it would be available, and you may miss a month here and there.
