What were you running behind diver, Speed? line type and pound test? We started running divers last year and had flea flicker line on with the same results. We switched to Trilene 30# test and do not have that problem any more. Don't give up! Since We started using divers we are catching more and bigger fish. With that said, you must understand that you can and will lose some tackle and lil troller and I always joke about pleasing the tournament gods with a donation of tackle to the bottom. You also need quality swivels and I think that the fleas can foul a swivel sometimes.
