Elk ,I know all that.I was wanting to take it a step further and get into the actuall physics behind it.


Like when an arrow front does get out of shape(like from torque).I know that fletching and foc will play a huge role in getting it back into shape but will an arrow with the same foc and the same fletching but one has 5 more ft/lb's of ke.The one with 5 more ft/lb will straighten out faster,OR WILL IT ?,Why is that?Is it because of momentum or is it because of ke.


Heavier arrows are more stable in wind and foc is a huge advantage.Why is it that a light arrow does great at 10% and you see traditional guys using upward to 16%-18% on their really heavy,slow arrows.They do nose dive but they seem to need the heavy foc along with the huge fletching.

Heavy arrow will need more stabilization on the back than a light.As speed increases,the need for huge fletching decreases.Just check Easton site on this.Is this because of the lack of ke in the traditional equipment?



See where I am going,much deeper than you need between 10%-15% foc and 4"-5" vanes.Or a certain arrow weight.



I know most don't give a rats %$# but it interest me.
