Everything that the others have said, smaller trebles or even a single hook is a must for them to swallow it but also, some use different leader types, I choose not to use steel leaders but rather a heavier pound flouro-carbon as much as 20 lb test for Pike areas or as little as 8 lb in more Walleye dominated areas. I feel that Flourocarbon line is more abrasive resistant then regular Monofilament.
