Shhhhhhh.......
I've pulled a lot of fish out of 20-35 FOW with these. If fishing deeper than 10' I break the bead off and tip with a spike or wax worm. Keeps the same action and when stuck vertical it seems to make the fish commit more. I fish them similar to a jiggin rap with a little more finesse, jerk them up hard let them flutter down flat, pause, repeat, pause a bit longer and look for a mark change on the bottom. Repeat the process moving down and up the water column, it may take a minute or two, but if jumbos are in the area they will get a glimpse of the glitter and come in like a freight train!
Ones with the bead up to the barb are no good over 10', the fish is going to shake the hook unless you can keep constant tension throughout the whole fight, that's a bit of a difficult task in 30 FOW. These are one of my go to baits when the fish are aggressive, if it's a slow bite they produce like any other flash type bait.
That's a quarter in the photo for scale.
