I need a little help from the pro's.

I am looking at all the different arrow shafts on the market and have this question for you. Which is a straighter arrow; one with a straightness of +/- .006 or one with +/- .003?

.003 would be straighter

again .oo3 are straighter but what kind of shaft material?
Strainghtness is only really revelvent past 20 yards...

IMHO, straightness does matter, but spine is the most important aspect of selecting a shaft. Buy the straightest shafts you can afford, but make sure they are spined right for your setup. We owe it to the game we hunt! Just my two cents. Be safe.

I feel overall straightness is more important than some do. .006 can mean total runout of .012. With fixed blades this may cause problems getting them to spin straight. And I feel that, generally, a straighter shaft is of higher quality. Higher quality means better spine and weight tolerances.

there really isnt much difference bewtween .003 and .006, I dont care how good you think your eye sight is you cannot tell the difference of 3 thousandths of an inch with the naked eye. with a micrometer set at .003 the jaws still appear to be completely closed. printer paper is thicker then 3 thousandths of an inch with a micrometer it measured .004. so if you really think 3 thousandths of an inch will affect your accuracy then think whatever floats your boat.
but honestly I dont think it will really matter.
