Has anybody ever thought about turning contact lens case holders into rattles like the versa rattles from whisker seekers you can put a couple of BB's and in it drill a small hole in it to run your line through or you could attach it to a sinker slider. I haven't tried it myself but do you think...

I recently was introduced to this rig last year, and never could find any videos on how to set this rig up. So I thought I would share how to set this rig up, and ask if anyone outside of this area uses a similar rig?
