I also pull 48 oz weights when high speed trolling for wahoo around 16-17 knots. You could always buy multiple 24 oz weights and clip two of them together to troll high speed, and then use a single 24 oz weight for speeds below 16 knots. Or you can also use 24 oz weights when high speed trolling if your lines are WAY back behind the boat. 24 oz are cheaper also. 48 oz weights which cost $27 a pieceWe use 32 and 48 oz but we are pulling them at 16-17 kts
