I just noticed that Sport Chalet sells packs of Berkley/Johnson Beetle Tubes for $1.09. You get 8 in one pack. I haven't had a chance to fish them yet but they feel pretty soft to me. What's the deal with these? They come in the yellow Berkley packaging but are these actually made by Berkley? At such a cheap price I wonder if these are generic-brand tubes that Berkley re-packages. I was curious whether these mini-jigs are any good. Anybody ever use these?
