Honestly...with all do respect. I dont think it has anything to do with your arrow..I think it has everything to do with your bow not being properly tuned. I say this because I used to be the guy who would take my bow to the "Bow tech"...Well after a couple bad expierences with the bowtech who really didnt know his head from his bleep. I took it upon myself to learn everything possible about a bow and arrow. That said I still have alot to learn. However, I do know quite a little about proper bow tunig and proper arrow tuning. They are both a science in themselves. Your arrow may be the perfect set-up but if your rest is even 1/16 to far to the left or right it can make your arrow fly sideways out of the bow. granted your fletchings will straight'n it but how much KE did you lose in the process? Thats just one very small aspect of a very very big picture.
