I think they are also. Single hooked, tubed over a bent shank or naked straight. Jigged in long sweeps or squided as fast as you can reel. I’ve caught everything from ground fish like porgy (scup) fluke (your flounder) blackfish (tautog...similar to your sheepshead) to pelagics including big eye, long, yellow and bluefin tuna. Hell, I even brought some tiny ones here to WV and have caught small and largemouth bass and walleye with them.
After my last post to you I made a list.....24 different fish!
They work well down here as well
