I have a Hooter Shooter (shooting machine)
I've always been envious of that..
and while I haven't tested this scenario, I'd be willing to wager that with my spine/straightness tester that you could find the 'high' side of those .006" arrows, fletch them all in the same orientation, and if they all had consistent spine from arrow to arrow- I bet they would group broadheads better than the .003" arrows if those had erratic spine differences.
But yes, if spine is consistent with both groups of arrows, obviouslythe more straight ones will generally perform better.
Maybe you can confirm this. I've found that straightness and spine consistancy have nothing to do with each other, when paying for better arrows.. Arrows that are rated at .001 were just as inconsistant with spine as those rated at .006 from one manufacturer. I haven't tested enough arrow levels at enough manufacturers to know if this is an industry wide thing, but I suspect it is from what I know about the technical aspects of carbon.
I'd also like to see the results of testing these arrows out of your hooter shooter, with real fast-spinning arrows. Lots of spin on a broadhead tipped arrow is something I really think is critical to great flight.
