Below is a quote from the titleist club fitting website www.fittingworks.com - seems like we have a long ways to go if they are fitting length of shaft to sweetspot contact - any comments?
Length
The proper iron length will allow for ideal posture at address and will result in the most consistent on-center impact.
The length fitting process will begin by testing a standard length 6-iron with face impact tape. Depending on shot distribution, golf swing, posture and ball flight results, the player will continue testing 6 irons at various lengths until on-center impact marks have been achieved and ball striking optimized.
The most common 6-iron on the PGA Tour is 37.5" (standard) followed by ¼" over standard. This is the result of good posture at address and maintenance of proper posture during their swing.
There are circumstances where a player's swing does not allow for on-center impact marks, and the ideal length will be determined by one that encourages good posture and the most consistent ball striking.
