As suggested by someone last year, get some black "beading cord" from a sewing/crafts place. It is like the elastic in underwear and replace the tubing with it. You will have to drill a little hole in the post, but it's no big deal if you have a portable press. I have been using it for this season and am well-pleased. It still assures you of a properly aligned peep, and eliminates the annoying rubber tubing slap sound. It is lighter than the tubing, so a little less string weight.
