I went and bought a dozen carbon arrows today and had them fletched with a right helical fletch. I am shooting through a whisker biscuit so I don't imagine it would interfere. However, when I told the guy I wanted a right helical fletch he said that his helical was a "true" helical. I told him thats what I wanted. My question is this, Is there a such thing as too much helical on your arrows and could it distort arrow flight? Or is a true helical what I did want. I didn't know there was a difference. I thought right helical was right helical the same. Thanks

What you probably got was a right off-set.
Unless they are on there like cork screws...then you could have an issue with too much drag.
If they shoot straight and group well...go with 'em

i have always sworn by hard right helical to stabilize heads and to tighten in the process. Good luck with your arrows.
