Moe Norman had one of the best strokes in terms of precision. When asked what was the most important thing he said "full extension back and through". When you think about it the extension is the extensor action and tracing of this point is back and through but there is another part of this where he says "full". The plane is infinate and the plane line is infinate also.... You should be trying to trace back along that line to infinity also....this way your hands will never be "out of bounds".

Tiger Woods talked alot about width when he was winning alot in 2000. I remember watching him drive a 330+ yard drive over the green to what to me looked like a super short backstroke (and woods has no flexability troubles...lol).

Jack Nicklaus said he took it straight back with plenty of width. Again this is the same thing.

I also think most people try to overload accumulator no.2 IMO. Leadbetter and other pop instructors from the golf channel have bought into this idea you need to set the wrists to a 90 degree angle yet if it wasn't for the front perspective distorting what you see, I bet you would see alot less than a 90 degree angle (more like 70ish) in historys best ballstrikers or they have a way to really stretch from the top to the end and load that accumulator to the maximum. What you are looking for is the purity of the clubhead orbit being onplane, not setting accumulators to the max. If the impact fix degree of flat and wristcock motion that is completely vertical is rigidly maintained during the entire stroke (1 of 2 ways I can see it being done) then the wristcock is also got to comply co-ordinately with no.3 with that plane because the left arm is above plane and the left flying wedge goes into the plane at an angle.... just like if you set that flail in 2k on the floor with a full wristcock and tilted it up - that clubshaft can't uncock into the floor.
