I'm talking about one end being out .001 compared to .004, doesn't make fixed heads fly like junk.
I am firmly on Danny's side. Crooked ends is why I have completely given up shooting broadheads on ICS type carbons. They shoot like crap. My aluminums shoot 2" groups at 30 yards. All the carbons I've tried - except, of course, ACC's - shoot closer to 8" groups.
