Yes I have heard of success with "Motor Oil" Colored Worms sprayed with Crab Oil. The worms were used with a 3 way swivel with two 3/0 "worm" or "circle" type hooks on the 36" leader and a 2 to 3 oz. bank sinker at the bottom depending on the current.
Bob....What are the details of your worm set up ? ? ?
Depending on the current and how fast you are drifting a 3/8 or 1/2 ounce leadhead should work fine. Just slide the gulp on the hook like you would rig a worm for bass fishing. Just make sure you get the saltwater gulp because the freshwater is packaged the same just labeled different. I prefer and red/pink or white gulp. I landed a 25" flattie yesterday on the red/pink along with 2 other keepers around 17".
put a 3" new penny shrimp on my hot hook yesterday fishing behind Avalon, had 3 small cuts looked like small blues bites on it after 3 hours... put a minnow/squid strip and started catching again... only the first time using it, but so far, bait got my vote... testing will continue though, just to be fair... did catch 3 keepers and a boatload of throwbacks on bait...
I have seen the natural gulp 3" shrimp catch allot of fluke this summer. I have also seen belly strips catch allot of fluke also.There is no doubt that they catch fish. I think if you match the hatch with the gulp they are deadly. In the same breath I feel if you continually change your cut bait it can be as equally effective.
