In case anyone else wants to try this. Started with wire and weights like clam did. Scrapped that after hooks kept fouling.
Junked the wire idea. After another few failures came up with idea of using drop shot weights and installing screw eye in bottom of crank bait lips. Used quick clips and split rings. Both worked but favor the split rings as hook fouling was greatly reduced.
For floaters with real small lips small bell sinkers seemed better.
In case you have not heard of this. It was to enable to use floating cranks for ice fishing. From my testing in my minnow tank it looks like an awesome idea. But the fish will have to be the final judge.When sinker hits bottom it emulates a minnow feeding. When you lift on the rod it assumes a horizontal relation to the bottom. Easy to imitate a swimming minnow action.
They have a few videos out on it.
If nothing else it gave me something to do while waiting for the ice.
