I used to fish our cottage lake with texas rigged (weightless) rubber worm and I caught a ton that way. Then 2 years ago I took some kid out on the lake and he fished a senko wacky. Even though I caught a good amount he outfished me significantly. Apparently an old dog can learn a new trick. I switched the next day and have never gone back. Originally I did use an o ring, but personally I don't find that they help. Without them, you lose baits as they get torn up. With them, you sometimes set a hook and just get your ring back (if the fish has only part of the bait in its mouth you can pull the ring right off the bait and its gone). I have caught pike on them as well as bass (and the occasional bite off unfortunately)
