Fact or fiction ???

The thoery is if you shoot a fixed blade broadhead, the blades should line up with the vanes. OK...now think of how the NASCAR draft works. How is the vanes supposed to do their job 100% at getting the broadhead and shaft to spin if the blades are cutting a path for the vanes to follow in. (through the air) Wouldn't you want the vanes to take control of the shaft no matter what size the blades are ??? And if the vanes aren't big enough to control the arrow(blades are steering the shaft like aircraft wings) switch to a bigger vane, or a more severe helical on your already non functioning vane ??? Or how many say...."it doesn't matter"

It doesn't matter, the vanes don't need to line up with the blades... ;)

I never worry about this either. I use a G5 ASD tool to square the ends of the carbon shaft, also after I glue the insert in as well, that's it. I also square the nock end. Spin testing the BH to make sure there is no wobble, done.

It's one of those things that can be true but isn't as necessary as it once was.

I'll try to explain.

Back in the day when "Prong Rests" were king. Many archers could only get decent fletching clearance if they stuck with straight fletched arrows. With straight fletched arrows that didn't spin in flight, lining up the blades absolutely made a difference. When the arrow flies without spinning the fletching corrects for "blade planing" drift only if the blades are aligned. So there is in fact some valid reasoning for doing this in that case. Fixed two blade and four blade heads were often hopeless with straight fletched arrows. Three blade heads took the market by storm as being more accurate, and they were.

Nowadays, with dropaways and "bristle" rests. Fletching clearance isn't the challenge it once was. You can put a good helical on your fletchings and really get that arrow spinning. The spinning action nullifies the need for lining up the blades. It corrects and stabilizes the arrow. If you got an arrow spinning fast enough in flight it actually wouldn't even need fletchings. It would stabilize just like a bullet.
