Double Hex

When you are fishing the Hexagenia hatch if you see splashy rises when the duns start coming off the fish may be taking the emerging insect rather than the dry dun. When I see this I put a Mr. Rapidan Emerger size 10 on a 36 inch mono dropper off the bend of a Mr. Rapidan Skater size 8 and fish this down and across stream to the rising fish. Some of the fish take the dry while some take the emerger.
