Just curious here. Was watching Bowtech's tv show and they were talking about properly selecting/setting up a new bow. But I did notice one thing. The guy who was shooting had arrows that were fletched with 3 blazer vanes but they were not all lined up on the same location.

The first one appeared to be where you would normally place the fletch. The next one seemed to be aligned an inch or so down the shaft (from where the first one was fletched). And the third was even further down the shaft.

They seemed to shoot fine and he had no problems.

I was just curious of why that would be done and what the advantages are?

As always, appreciate the insight on this board.
