i am doing basic motion 10days now.i hit an average 500balls over the day into a net and i must admit the motion becomes second nature once you understand and familiarise yourself with the movement.my background comes from track and field and i spent years in UH texas under the guidace of tom tellez.he had us doing specific movements and i think this is why i'm grasping these movements of TGM so easily but with aot of hard work.
from my short time of practice using TGM personally i find hitting during the basic motion far superior. WHY? because i know and most importantly feel the positions while hitting.i can feel and hear the compression and crispness of the stike and also i can feel the FLW.the hitting motion is very very similiar to a karate move which i have firmly place in my subconsious mind.
last but not least on the AL dvd lynn demonstrated a drill by simply using your right arm to move your left.i think its called "the magic right forearm" and he also showed a fuller version on VJ which both are superb.
for me i'm definitley pointing to hitting because of the feel aspect of the movement
