Leafing through my cabelas cat. I noticed that some fletching seemed to be about half an inch or so from the bottom of the nock others seemed to be as much as maybe an inch and a half or more. Is there an ideal placement for the fletch or a rule of thumb, or does it even matter? And that leads me to the question I was originally going to post.. can I use blazer vanes in my blue Arizona EZE fletch successfully?
