Question 1- yes, I ended up buying a taylormade m1 last year when you had that interactive chart comparing the M1 vs the Cobra King. Knowing all my swing stats, I could see the M1 was the better fit for me- then I went and tested both clubs and found my stats matched almost to the number with your chart.
Question 2- mygolfspy has opened my eyes to reality vs marketing BS that all the companies use.
Question 3- hard to say as lessons have certainly helped, but the hdcp has dropped in last year from 3.4 to 1.2. I stripe the M1 so that correlation can be made.
Question 4- yes, fairways are way more fun to play out of than the rough.
