I've been tying for almost 8 years and have always used head cement. I usually use some type of super glue or zap-a-gap and and apply it to the thread, make three turns, then whip finish. This works well for me and I'm not sure I will stop unless there's a good reason. I'm just curious about those tiers who do not use head cement. I've read several times that if you "tie off your fly correctly" there is no need for head cement. I use a whip finisher and make at least 3 wraps with it. I guess I'm asking what is the "correct way" when not using a head cement. If I don't have to use head cement, and if the fly will not fall apart, then I see this as a step that can be dropped. For those who do not use head cement, are your flies as durable as those who do use cement.
Thanks,
Greg
