I make my own fishflash out of road sign thickness aluminum with silver prism tape on one side and spray paint on the other - nice bright green is the best color and a lot cheaper than the tape. Just take the measurements from one in the store. I put 6 bead swivels on them with plug snaps - these don't clog up very easily with weeds like a single swivel, even a Sampo, will. These are just a touch heavier than plastic so you will need a little longer dropper if using them on the bottom in the CR for springers, but the rest of the year I run them on a diver and so don't worry about it. Fishflash work better than anything else shallow, but at depth I prefer a luminous hotspot.
