Ok guys here goes, I used to shoot weight tubes to achieve desired arrow weight. I haven't used them in a couple years but I am going back to them, nowadays you techies have all these new programs to check all these variables in your arrow set ups....
Here's the situation....I am shooting Gt Xt's 7595 at 29" out of 70# bows (in my signature).....I am wanting to add 3gr weight tubes to get my total weight up to about 450-475gr.....I can't think of anything that this will affect, however I know some of you, have all these different calculators that I would love to have access to....Also I would like to know if any of you have any opinion's on this move please let me hear them!!!!
