Hello gents thought i would try and pass a little info to you guys, you may all ready know about it but if not it is a pretty good tool. it is on eastonarchery.com it is an arrow caculator that will tell you what each type of thier arrows ways, and you can add fletching wieght, nock wieght ect.. and it will let you know what the hole arrow till way.

And for you energy freaks out there, there is also a kinitice energy chart. you put in the weight of your arrow then how many fps you are it and you can see what the energy out put is for your arrow.

It should help out the guys that think if you shoot a bigger arrow at slower speed you will get more energy. anyways it is in the download part of the wb sight at the top right hand side of the sight. hope it helps out.
