Not quite sure if I buy what your tech is saying. I would go as far as to say that fletchings are not that expensive and that I recommend trying some and seeing for yourself. I also think that you may want to be concerned about what kind of broadhead you shoot in wind like that. Esp on long shots. The key is to find what combo works best for you and your type of hunting.

Ed, I totally agree!! Nothing like experimenting and finding answers for your rig yourself. I have played with a lot of different fletching combos every year and this year will be No different. I may even set one Bow up using QS Speed Hunter ST's, as they have impressed me in the past.
Feathers usually win out for me though.
