If you look at the Bobby Jones single strobe pics, you'll notice there seems
to be almost no hand rotation of the shaft before impact. His hand position
on the shaft is almost identical at address, at the top and at impact. His
wrist cock maintains the flat back of the left hand he has at adress. The
club stays on a straight plane. The rolling hand action looks to happen
after impact. Am I missing something?
Here is another example of the "measured, quantifiable" versus "anecdotal" which continues to dog our pursuit. Jones does not roll during the downswing and likely doesn't roll in the backswing. Many other player's/pro's may not roll either yet many others do or believe they do. If so, then this is another variable to account for in the swing. It may be that the simpler the swing the better. If rolling is occurring then the variable of that timing may cause more inconsistencies in the shot than any shaft/spine variation. Much more testing to be done.
