The comically named "Grandpa's Eggs Fly" is an interesting "double take" on the ever-popular Nuke Fly. I use this fly primarily when fishing southern Ontario's Saugeen River. This river tends to get coloured in the spring, making larger flies easier for the fish to find. I find this fly particularly useful when surrounded by center-pin anglers drifting beads—Grandpa’s Eggs tends to stand out from the crowd a little more than your standard yarn pattern. It is simple to tie, but make sure that the two eggs are lined up so the fly doesn't helicopter during casts. When you’re having a slow day, this is a good fly to try.
