Actually you do not need Flo orange for after x-mas archery or flintlock. It is "encouraged" but not mandatory. Here is a clip from a PGC news release - I will also attach the website - it's near the bottom that this is addressed:
"...Hunters using archery or muzzleloader licenses, and hunting with those special sporting arms, are not required to wear fluorescent orange clothing while afield, but are encouraged to do so. Special regulations area hunters must wear 250 square inches of fluorescent orange clothing, unless they possess an archery or muzzleloader license and are hunting with a bow or flintlock."
