You should just tie your line directly to a piece of yarn. Don't even use a hook if that bothers you so much. Or better yet, stay home. C&R is just fine, I'm all for it. I've never killed a nate, but have no qualms with those who do. But when I go fishing, my purpose is to catch a fish. If bait is working, bait is what I use. If jigs work, I'll use jigs etc. I do recommend barbless hooks, but when it comes to lure/bait selection, I'm not going to intentionally hamper myself.
