Since we are in full dry fly swing here in Colorado I thought I would write about double fly rigs and how two is sometimes too many. A lot of anglers fish with two flies for all fly fishing applications. Every fly fishing rig you look at, whether it be streamer, nymph for dry, seems to have two flies attached to the bitter end. Although I have used it in the past and will use it again in the future I prefer casting only one fly when I am fishing with dry flies. And here is why. I feel like a single dry gets a better drift than a double fly rig. It seems that one fly always sinks faster than the other and drags the other fly down with it. It drives me nuts when both flies are floating two close to each other down the river. This results in delicately mending while trying not to spook a fish, which ends up pulling the flies out of the “ZONE”. You cannot be as accurate when casting two flies. A lot of times, especially this time of year, fish are tight to the bank and rising underneath overhanging vegetation. Putting a tight loop into these spots with two flies is a daunting task and results in flies hung up in the overhanging trees (at least when I am casting). Many people fish a big stimulator trailed by a smaller mayfly imitation. This is great for many fly fishing applications but it really limits your ability to fish the stimulator. Bigger flies move when they are on the water, hoppers, crickets, caddis, drakes, etc.. so when I am fishing bigger stimulators I find that fluttering/skating them across the surface tends to draw some aggressive strikes. When you are fishing two flies it is difficult to mimic that natural skating movement larger flies tend to make when they land on the water. Although I am beating up on the double dry scene, I cannot say that I do not employ it time to time. When there are days that multiple hatches are flying around, like caddis and yellow sallies, I might tie on one of each and see what they are keying in on. Double dries are also good for anglers who cannot pick out a smaller dry fly and use the bigger bug as a locator. Hey its just fishing and it is all good. Personally I just prefer the single dry and maybe its worth trying during the next big hatch in Colorado.
