You mean Turbo nocks outweigh 3, 4" vanes and a standard nock by 25 grains?? If you don't mind my asking, what's the FOC for those two arrows?
Don't know the FOC Art....irrelevant to me. They fly straight and hit where I aim. Arrow flight is good although I never bothered to paper tune them.
Dwaasp...I didn't understand a thing you said brother. [:-]
