are you using king rag or maddies? king rag are pretty much a waste of time on this beach for the flounders. try a section of black lug tipped with half a dozen maddies on 3 foot hooklengths. you should avg. about 10-12 fish a trip. my best being 33 fish insize in a match last year or if you move up the top of the beach by the look out tower you will find a lot more bass, caught 17 there in may in one session all schoolies but a bit of fun.
Using King Rag and lug I dug on the beach - yes maddies are excellent bait for flounder but I was really after Bass. Had a nice 5 pounder couple of months ago on king rag and every tidy fish I've had since has been on the same bait.
