I got my first one last year, and so far i' ve had 3 this year alone. 2 on my own arrows at 30yds and 1 sooting 3D on a friends arrow, Man did he whine and cry about that one. But what made it even funnier is right before I shot I looked at the target and said in a sarcastic voice " Now which knock should I hit?" And I ended up Robin Hooding his arrow. It is a great feeling to be able to do that but it is a pain to get the good carbon arrow out of the busted up carbon i' ve just shot.
