I am pretty new to bow hunting and am wondering about how much total weight I am shooting. I have the Cabela's Stalker Extreme arrows 65/80, they are 28" and 9.3gpi. They have blazer vanes and I shoot 100 grain broadhead. Can someone let me know how much weight I am shooting and how you come up with it? I'm not sure how much weight to give the nock, insert, etc, etc. Help would be appreciated. Thank you
