Still stewin in your juices 12PB...agree with the bits I understand so far - but what do you reckon to the green stuff I added above...do many angle of approachers really shorten their shoulder turn...or do they use top arc bit....something like that post Yoda did on KJ CHoi about a year ago??
I'd say watch somebody like a Snead or Bobby Jones . . . Some of this has to do with Plane Angle as well and the depth of the hands/whether there is a bunch of lifting going on e.g. Furyk . . . . in addition to all that the rate that #4 must release to stay on the selected plane too . . . . and there are probably some assumptions with regards to the "inscribing perfect circles" as mentioned in the first part of 2-H.
Pretty sophistocated subject . . . . probably beyond my level of sophistocation.
