can anyone help tell me about joints and their feel. i was looking around online and saw some joints with a 5/16 14 piloted ss joint. i was wondering about what kind of hit this puts out and how is this different than a regular ss joint. also what is the deal with a wood to wood joint with a radial pin. ive been hearing this helps create a more consistent hit. also i have seen a couple cues with a flat faced joint, what is this really?? somebody help explain this to me...........
