Truth be told, I'm a GOLFTEC coach and you totally misrepresented GOLFTEC here.
The colors you referred to are a lot more important than you are leading onto. They represent the TOUR averages for 4 key motion measurements--hip and shoulder turn, tilt (not spine tilt), bend and sway.....and GOLFTEC's knows the tour averages for each motion measurement for each part of the golf swing (and there are 9 parts). Green colors are Tour averages, red colors are the worst golfers averages, yellow colors mid-to-high handicapper averages and blue colors are golfers who swing too inside to out (overdraws). GOLFTEC had two other key motion measurements almost never talked about---lead elbow flex and trail knee flex.
Not sure why you weren't impressed with the club fitting as they are among the best in the nation and rarely push aftermarket shafts (knowing that the stock shafts on the market are good enough for 99% of golfers out there).
