RonS,
There are two more sets of launchers besides the ones on the rest. I' m not sure what they are called, but one set has the slight forward curve and the others are the mantis shaped ones. I would consider these more for target/3D shooting even though there is a set of teflon sleeves for the curved ones.

There was also a note in the package for me to call GKF and they will send me yet another set of hunting type prongs and some sort of arrow guard.
