Back before the plastic baits were wiggling and need more action, we would tie our mainline to these spinners, and then hook the spinner to the hooks buried in the plastic baits. We would also use these spinners with live bait, lip hooked mirrors, head hooked nightcrawlers ( with their tails full of air ). We did this mainly while chasing walleye back in the Northern Midwest. We used Long LIne, Lead Line, and Mooching styles of "back trolling"...
Yes, because the blades were so small, they couldn't make the whole bait dance. Their job was just to add flash and attract the bigger fish ( walleye & sometime a Northern )...So the hook was attached directly rather than hanging back a ways?
