I'm going to try the little balls more this year, I use a rubber band looped thru the loop of the leader that I push through the hole - sounds funny, but simple and floats pretty well. I've also made up quite a few of the yarn indicators that don't use an o-ring, rather just a loop of yarn with thread passed around the middle about 15 times and tied off. I had a lot of these last year that I didn't get around to using till I lost them. Love Thingamabobbers, but am not convinced they don't scare the fish, especially the way I cast.
