I've been messing about trying to tie bug-bond buzzers incorporating an exaggerated thorax of booby foam to get different sink rates. I don't know if what I've got will catch fish, they're a bit peculiar looking, but look forward to giving them a try. I'm not trying to make a suspended buzzer, although the one that does float actually doesn't look bad from below.
Here's a video of a standard buzzer being dropped into water, followed by three of the new ones.
What do you think, an idea worth trying out, or just a midwinter crackpot notion?
