The spot I am working on is an elevated isle in the middle of swift current. It's a bit tricky to get there, but I'm convinced it will produce. I've tried it already this year. I lost 6 rigs out of 7. The area is swept of sand so the rocks are heavy on the bottom. I considered how to get the bait exactly where I wanted it and not loose the rig. The rig I considered is basically a big float (balloon) and a big weight. I figure a sparkplug or two should get me near 4oz or so. I will not need to cast this rig. I can merely drop it into the current and walk it into the slack water's tail. I have been unable to clearly gather the depth I need, but I fugure I can adjust it until the weight is just off bottom. With the tight line between the float and weight cause a problem for the bite? How long should the extension to the hook be? I was considering 6" shorter than the extension to the weight. Your thoughts? Is there something simplier I should try first?
