"If you're cued with casting multiple lures you can try using all three together... use a leader of around 9 feet. Attach one to the point, one midway on a short dropper, the last at the swivel end, again on a dropper.
I once had all three with bass on at once... it was a nightmare as they all headed in different directions. Tip: use a tapered leader to minimize the middle one fouling the lot."
He has had some new ones arrive, and let me have these to try for cheapo, so worth a go I though on the Injection.
