Cock fletch orientation

[Pappy]

I set mine up like the picture Woodely showed. Without a shelf I guess it wouldn't matter, don't think it matters much anyway, but as with my broad heads I just like to do them all the same , years ago Black Widow showed this set up and I just stuck with it.

I believe Pat and Tuomo are correct. The fletching will never touch the riser "IF" the arrows are tuned to the bow.

OK good point;  but am I supposed to doubt all the articles in my Archery Magazines written by Bowyers and Archers about arrow and shelf contact.  These guys all say the same thing minimize arrow contact.  I would be held ridiculously silly if I doubted these people that have over 40 years of experience.   

They do not write magazine articles for their health,  they are simply sharing their experience and knowledge.
