Tongz.. very well done, excellent post, although I heard that from you many many times from you over the phone.
Quick question the mop drill, could we say that it is more like a Hitter's drill rather then a swinger drill?
When Hitting -- Drive the wet mop through Impact using muscular Right Arm Thrust, which is directly felt through Pressure Point #1 and #3.
When Swiging -- Drag the wet mop through Impact by turning your left side against your Left Arm, which is directly felt through Pressure Point #4 and indirectly felt through Pressure Point #3.
Either way, it's deliberate, positive and heavy -- constant Loading, constant direction.
