I really like using the FAF & FAF 2 in my duck decoy spread. With a little preventative maintenance, they will remain in service. Only problem is with them flipping upside down in the water. This is generally only a problem when setting in deep water (tossing out of a boat) or with dog swim-bys. Anyone tried modifying by adding a keel? I'm thinking about epoxy and a hollow PVC tube to the bottom (water keel); maybe add a little weight to the bottom of the PVC tube.
