Guys you have select the proper carbon shaft so you can get what you want out of them. If you want speed for 3D shooting then go for the light shafts if you want the most in penetration then go for the heavy shafts.

There are carbon shafts out there that weigh anywhere from 5.5 grains per inch all the way up to 15.5 grains per inch and all weights in between.

A 2219 weighs 13.7 grains per inch.
