i am totally new to this type of stuff. i want to learn as much as i can. i just went with the pro shop set me up with. i shoot a 350 maxima hunter weight forward with a 100 gr tip. At least that is what the arrow says it is a 350. so that means i am shooting a 450 gr arrow? correct? i should be setup pretty good shooting an 70lb admiral w/ 29" draw?
