Rigs
I started with the classic wire Safa rig. It doesn't always swim right and the last hook is too far forward for my liking (you miss a lot of hits). Then I found Carnster's button rig, but somehow got it wrong and created my own using a top hook instead of a bait spring. I tried the bait spring but realised I preferred the top hook. Then I got tired of attaching led to the top hook so I started using lead that I could simply thread onto the top hook and swap for lighter/heavier weights if needed. Then I wanted to be able to swap hooks out as they wore out and/or to make the rig longer/shorter, so I made the rigs modular. The last thing I've been trialing is to move the weight off the top hook so that I can rig pilchards (sardines) upright, without having to puncture the belly. It's still a work in progress.
