Is there a stiff side to carbon arrow? I have these grizzly stik sitkas and I thought I seen some place that you can determine the stiff side of these arrows by putting them in water. Does this make any sense, or did I just imagine this post?

Nope you can plug the ends and the weak side will float to the top.

You live in the prefect place, just run on over and talk with Ed at Ak Bowhunting Supply.  I am sure he will give you a hand.

I have never tried the water, but it does make sense.  You could use this for any type of shaft.
