The way I look at it, any new arrow is going to be straight enough to out shoot the shooter. Or at least in my case.
I try not to buy anything past .003 , for instants my Ultralight 400's are .003 My arrows are 26 inches so I cut that out of the middle of the raw shaft . A Gold Tip rep. suggested this over spending the money for the Ultralight Pro's . Seemed to think it made the arrows closer to the .001 tolerance of the pros . Seems to work for me .............. but I am not saying this is 100% accurate on making the shaft staighter , but it works for me :thumbs_up
I only difference I can tell between goldtip pro hunters .001, and the expeditions .006 is about $60 a dozen. They will both shoot as good as I can out to 50 yards with a 100 gr. muzzy.You know I dont really care about straightness. I used to spend 120 bucks on Carbon Express on +/-.001 arrows and truthfully they shoot just as good as 50 dollor Gold Tips which are +/-.006 im shooting now. I really dont think the straightness effects the arrow flight that much, and I still have no problem shooting out to 60 yards.
