Hey Guys. The rubber bands work great for dinks, but you have a solution for the balsa and cork stem floats right under your nose. Just cut a couple of pieces of surgical tubing about 1/4" long, and run your line throught them when you rig up. Secure them over the top and bottom stem of your float, and you have a very quick way to change depth without line abrasion, and also a quick way to switch between floats. Been doing it for years, and it works great. Also great for light line, when you got the kids out somewhere fishing for sunfish or crappies with a float. 6 inches of tubing will last you most of the year. Good luck
