I couldn't co-ordinate this one for a period a while ago.....it just wouldn't feel natural or "synced" or smooth at all. All I could do is PULL from the top of the swing. Now "the drop" move is pretty easy.
For me what has worked:
1. Drop........
........then......
2. One of these:
-"left shoulder up"
-"shake the sugar"
-simply- "hit it" (with both hands)
For me if I simply do this it naturally drops down the TSP...........but then there's the Machoman Randy Savage Version.............that being The Elbow Drop (down the Elbow Plane) of course.....
Other ideas for #2:
-fire hips
-pivot
-shoot the marble outta the tube (this is Brian's from COFFlipper)
-etc. (Brian will have about 9000 surely)
Not sure if there are any drills or if it is mostly images/feels.
