These monstrosities will take big largemouth too, you just have to cover more water than with smaller flies.
I tied these hoping to get some likeness to a peanut bunker, but I'm sure they'll do fine whenever bass or blues are feeding on rain bait.
And finally, sand eels. I've tied a bunch of veriations but to my eyes this looks the fishiest. Sparse flash, sparse marabou, and just a bit of fine secret synthetic. It looks goof, but the fish will be the final judge.
