Sounds like he is rigging them up like a saltwater plug with the braided leader. I would think with that short shank a 510 wouldn't do well as it wouldn't be wobbling straight with the short shank. My big ocean plugs have huge open rounded hooks. They are 8/0 and 9/0. Wonder if these are too heavy for a Kwikfish? I would think offsetting a hook wouldn't work with a plug as when the fish bite down it, it teeter totters over the bottom of the plug. If the offset was facing the wrong way the point might be up the side of the plug? Some guides swear by the 510s. I put them on my Kwikfish but have not tried them yet. Hope this wasn't a mistake. A couple of years ago I bought some Tomic TNTs. I tried one for the first time at the Roche Harbor Derby. They reacted like a Kwikfsh. I have them in Mother of Pearl, Army Truck and other colors. They have multiple holes in the front to thread the leader through to change the action. Has anyone ever tried these before? They are dish shaped from side to side (shoe horned shaped with out the return lip).
