Ok,so I have a 45lb Savannah. I bring it to my local trad range,and the guys check it out ,try different arrows through it,adjust nock point brace height etc.. most of them conclude the 2016 is the way to go. So,I buy Gamegetter 500`s,equivalent to the 2016? I think... Anyway.. I start shooting them and I get alot of left to right movement at the back of the arrow during flight. I ask one of the guys to shoot the same arrow off my bow,and it flies well. So I have to assume it`s because I am new and my release is not that good yet. Or,,is it because he has a shorter draw length than me? Anyway,,today..I ran into another guy I know there,who shoots 1916`s. I tried em out,and they fly like darts off my bow,,no wobble just straight! So,, I ask you..did I choose the wrong arrow? I am goin bonkers here.
