Hi John,
Chopped fiber and silica will give you stronger fillets than some of the other commercial fillers, such as microballons. I don't know how wood flour compares, but I suspect it is pretty close to chopped fiber. WestSystem has a whole product range of fillers, some of which are intended only for non-structural uses, and their literature has some good discussion of fillets. But in our kayaks, loads are really small and bond areas are pretty big so just about anything will do - especially in stitch-and-glue construction where the hull fillets are covered with glass.
