I have checked 5-6 dz of the new Bemans some Max 4 and some Black Max arrwos and the worst out of these were .011. and one dz I checked were Max 4 340 and they were all within .004 or better.
That has not been my experience with Bemans. The ones I tested were much worse. When checking aluminum arrows, I'd get at least .003 to .004 difference on a dozen. None of the carbons I've tested have been anywhere near as consistant. For them to test better than aluminums seems unlikely at this point in their development.
