Love Len Thompson spoons and still use them. My favourites are still the spoons made by Dam Effzett. I still have a half a dozen 74 gram ones from the 70's that don't show up anymore on their websites. Great for Lakers and Pike. Seems they are popular for Tigerfish in the Zambezi. Might have to go where the River Monsters guy went! I do seem to remember Kitimat making Effzett knock offs way back when.
