I was practicing casting in the garage at work (I work hard, I know ) And had what I think is a really good idea. I didn't want to throw lead or lures with hooks on them around so I took one of those big pink erasers like you used in grade school and pushed a paperclip through it to tie my line too. Basically a really cheap practice plug. Nice thing about it (other than being cheap) is that its soft so you dont have to worry about beaking stuff. Another nice thing is that with a kitchen scale you can use scissors and cut in down to get any weight you want. I just thought I'd share in case anyone else could use this idea.
