I fished Head earlier this year. The fishfinder went down early in the trip (bad connection) but we still managed 2 eyes on crawler harness close to the launch. There's LOTS of really, really thick weeds, so try to find edges.
WFN is incredible! I don't see how anyone can stand Chronzy though. He patronizes the hell out of all his guests and fishes in areas that you have to have next to no skill to catch fish.
I walked all through that conservation area with a fishing rod looking for a place to fish. Boy was I disappointed. The scugog river has muskie, bass, and walleye in decent numbers all year.
