If by chance you do hook a 4-5 ft shark in Horry County, it would be cheaper to just cut your line. Especially if you are afraid of being tagged. The shorter the shark, the more flexable they are. Just because you have it's tail doesnt mean he still can't get you. If you are just fishing the surf for flounder, reds etc. chances are you're not really using a heavier rig (unless you're targeting bull reds) odds are you won't see a 4-5ft shark. Also, if your tackle isnt set up for 4-5 ft sharks, you won't have to worry at all. (they will break your tackle or your line).
