Or, "maybe" they wouldn't want to disclose that something like the straightness of .006 vs .003 vs .001, is so minor that they prefer the consumer decide for themselves if it's really working better for them.

I personally would "assume" that all things will not be the precisely the same, with only straightness that an arrow being different. I would expect arrows having .001 straightness would probably, more importantly so, also have a tighter matched spine and consistant weight than the lower end .006 arrows
x3 Well said.
