Use Cralusso torpedo for nailing bait still, with a couple of feet of line on deck with droppers. Plumb up so olivette is just off bottom. Get an adjustable spray bar or feeder arm with a narrow rod rest head to hold pole, then move feeder arm up or down leg on seatbox to get right angle of retardment between pole tip and float bristle. You just want three or 4mm of bristle showing. When it goes under, a small lift and the fish should be on.
For edging through, best floats IMO are Cralusso Bubble pattern. Cralusso do a huge range of sizes for each float model.
