"Nothing wrong with striving to obtain optimum arrow flight to increase the likelihood of better penetration on game and, ultimately, a short blood trail and quick recovery."
No, but there is nothing wrong with not bareshaft testing arrows. I have never done it and can acquire perfect arrow flight. There is nothing I hunt or shoot at without feathers, so I fletch my arrows, then I tune them. It works very well and will accomplish anything bareshafting will.
There is always more than one way to accomplish a task. Frankly, I think we are creating more jobs for therapists then we are creating good archers.
You do not need to bareshaft your arrows/shafts to get great tuning and perfect arrow flight.
Anyone who wishes to see how us old pharts have managed over the decades, please contact me and we can get together on how it's done....simply, effectively.
