I'd give the fish pimps a miss too, they come off far too easy. The turn-on type given two or three twists ( you'll know what i mean when you see them) stay on and stay where you set them.
I like to give them a long slow pull every now and then to raise the buzzers up the water and then let them drop, you get a lot of takes just as moving one way or the other, that's what the natural ones are doing, they're always heading for the surface and changing their minds and going back down....
But you will get the odd one that nails the indicator, give a quick long pull to get the top dropper where the bung was and they often turn and take it though

or tie up a deer hair ball in whatever colour you fancy, then you have an indicator with a hook, but not so easy to adjust depth, so start with bung find the right depth then swap if they are attracted to the bung a lot.
........ or just dead slow figure of eight with no bung at all.....also good on its day
