The Decoy Pluggin' Singles are designed to replace treble hooks on lures with singles. They have an over sized and upright eye to allow for the split ring.
Many anglers prefer only having one hook in a fish, rather than a treble to contend with. Other advantages with the singles is that they allow the lure to work more freely
I've found the Bass to be pretty preoccupied recently with very few taking my usual go-to lures, then I got these - I took the trebles off (I don't like them) and just use with the assist hook, they cast like a bullet on my LRF setup and in two evenings I've lost count of how many Bass I've caught with a few Mackerel and Garfish thrown in for good measure. I'll definitely be getting more
