Very true. BT is a process and it can be used with any release, even bare fingers. The release your referring to is a hinge or spike style release. The main thing to remember is the release is fired by the movement of your elbow, not by squeezing with your fingers or rotating your hand.
BT requires dedication and practice to learn correctly. If your willing to put forth the time, you will be rewarded with increased accuracy and confidence. If your serious about learning, get with Pinky or myself and we will get you started out right.
