True, but when talking about bigger flies, especially those with hair wings, head cement is still not that useful, and epoxy becomes very important. However, the original post/quote obviously dealt with dry flies, and in that case I tend to agree that head cement is not needed in the majority of ties -- although the effect on buoyancy is overstated in my mind.

The commercial tier's point of view is a bit misleading because economy of motion becomes important where a non-commercial tier can be more concerned about durability. Head cement used throughout a pattern can have a very significant effect on how long a fly lasts.
