I had some exactly the same as that. Well, as good as my fading memory can recall. I lost the goldy one yesterday trolling it at Iron Pot. My last one. I did have some troubles with em swimming on their side. I found that (a) slight adjustment of front wire and (b) a brass swivel about a metre up the line adding a touch of weight helped my dudes to swim really well with that little vibration that told me they were working well. Even caught some fish.
Yah, I was right. Do I get a prize? Wait, I will get my own prize. I will eat another of my health bars (read chocolate block) and when me missus looks at me with THAT look, I will say that PeterJ said I could.
