Ordered some flies the other day through Fly Deal Flies via a referral by Bill (who also writes the Fishing Through Life blog). Although I haven't received the trout flies I ordered yet, I did receive an introductory letter from the retailer with a free sample of 3 size 18 Firebug midges in it. Found them to be very interesting, if for no other reason than the rainbow of colors.
Don't know if they catch fish, but I planning to head out tomorrow morning to give them a try. Hopefully I'll be posting some photos of trout with orange zebras hanging from their jaws.
