You might also try bead chain. If the drift is as slow as it sounds,bumbell eyes would probably be too heavy anyway. Another thought would be to try A keel hook. the weight goes in exactly the right spot and is easily adjusted up or down by using those lead strips that come in the matchbook format. A possible downside to the keel hook is the ones I have seen anyway seem to be A light wire. But surely worth some reaserch.
Your pattern by the way is awsume. I tied A couple of them today On A 2/0 Partridge 10xl h/w streamer hook. We are talking serious iron here. we have some 50 in. Tiger Musky here. This will be my first year to fish these guys.
ps; If A man is talking in the woods and his wife does not here him, is he still WRONG?
