i thought i read somewhere that a good arrow will only rotate 2-3x in flight...distance plays in of course...but i thought i read it some place that they dont rotate as much as we think...

i dont really think that because it stops spinning it looses much energy at all...the main motion of the arrow is a forward motion. its got a ton of energy all moving it forward...

i can see weaker arrows flexing more upon impact and not penetrating as well as a stiffer shaft...
