So why didn't he make the switch? I guess I will never know for sure. My best guess is that a traditional model design that was already in the product line would be easier to sell. In the Pro/Endorsement business as much as we want to think that player's use what is best for their games, it doesn't always work that way.
One thing I find interesting in the interview. He blamed his path and what he saw on Puttlab for his two way miss. He is making the same mistake that many do when confronted with the reality of the measurements. Instead of looking to what actually causes the problem, they focus on what is easiest to see. The math is pretty simple 83% face 17% path. Why fix the 17% when the 83% is the problem? Especially when the path is consistent?
