Vented vs. Non-Vented

[CRS]

I would not call it a whistle, just air noise, similar when fletchings are too big.

That is why I prefer 4" fletching, and the big bananna cuts are out, unless I want to aggravate other shooters, while chasing X's.

We strive so hard to be quiet and limit noise while hunting.  From our apparel, to our bows, why not have the quietest arrow also?

Jeff, I am playing with the VPA 160gr glue on.  I put this on an adapter for a total tip weight of 240gr. This is on a 26.5" axis arrow for a total arrow weight of 480gr.  My bow is a Centaur Carbon, 58" 52# @ 26" draw.

Chad, I agree with trying to be quiet.  I have had great luck with my current set up and if I can't get the flight just right with the VPA I will stick with that, just wanted to eliminate the air noise, so to speak.
Thanks all.
