Make sure you have a few good bunker flies in the mix. deceiver variants like Page's bigeye baitfish are a good bet. Don't forget the success Hawkeye had with his slab profiled pattern with emphasized cheek plates (like a feeding bunker!).
I still have success with the real eels in bright colors during the fall especially in the surf around Charleston, East Beach, Napatree, etc.
If you have the livebody, a few big poppers for low light in the surf is a plus. The local pluggers yank some huge cows from the surf with poppers. I plan to be chugging a big banger in the surf this fall for sure, maybe on the two-hander in the big sloppy surf.
On the inside around Watch Hill, silverside patterns are the key especially if you're bored and want to keep busy with the plentiful large shad. Unlike stripers the hook must be a large percentage of the fly body for shad. Stripers make a run along the inside wall too, making for some easy entertainment at first light and dusk.
I hope we get some blitz action like the past years, can't see why not!
