I could write a full page on this.......but anyway......I used to worry myself to death with this. I was really worried that .003 wasn' t straight enough.
In actuality I had never even shot any .006 arrows. Well if you shoot and hunt a lot .........you know arrows get broke,lost,etc. and a .006 arrow will shoot plenty good enough for anyone hunting .Since most aluminums are straighter than that.......I assume your looking at carbons. I suggest you try some GT Hunters or PSE CF Dominators........I' ll garentee you that you will not see a noticable difference in your accuracy and you will sure feel better if one gets broken or lost or whatever !!
