the gulp rag works very well for bass and pollock fished under a float, i think its the movement of them moving in the tide beneath the float rather than the scent that atracts the fish. a couple of mates have had superb results for bass on them, seemed to outfish fresh rag !!!!!
i have never been a artificial bait fan but results speak for themselves. i have seen various gulp bais fished more conventionaly on the pier but they fished nowhere near as good as fresh bait although i have seen fish caught on them.
