Who aligns the blades of the fixed blade broadhead with the fletchings? I have gone back and forth on this over the years and it seems that it really does not matter as long as your blades are aligned eitherbetween the the fletchings or in line with them.
I know I could probably get better flight with an expandable but I just can't let go of my Muzzys. They reallyhammer 'em!

If it ain't broke don't fix it. If your way works good for you stick with it!

The only thing I ever check for as far as blade alignment goes is that I won't hit the riser or my sight. As far as mechanicals go, well that is another subject entirely

Absolutely does not matter.

I don't get that statement, I get perfect flight with both mechanicals and fixed so it's not the broadhead, it's the tuning.
