I'm still wondering, if the point to fletching is to create drag on the end of the arrow, wouldn't we be better to fletch counter to the way the arrow wants to rotate?
I mean, ideally the fletching is there to fix our screw ups, that's why we tune with bareshafts. So the idea is that drag fixes our screw ups.
Wouldn't counter to the natural rotation produce more drag at launch? Correcting the arrow?
I fletch for the direction my arrow spins, but this is something I have been pondering.
I think it's something that would show up less with a shooting machine, more with an actual shooter that can have flaws.
It's like using a heavier helical.
Not saying I'm right, just thoughts for pondering.
