Bear with me here, I have had the hardest time trying to switch from a strong grip to a neutral grip and the big problem seems to be my left thumb. I physically cannot make a "short" thumb on the shaft and I wonder if that is why I seem to need a stronger grip (i.e. in order for the thumb to be where it needs to be in the swing). I remember an interview with Jack N. where he talked about the characteristics of the left thumb. He said that with the exception of Arnold Palmer, all the best golfers had a left thumb that "curled" when you gave the "thumbs up" sign and this allowed them to position it in the right spot at the top of the swing. I'm just wondering if I should give up trying to go to a Neutral grip if I can't get my left thumb in the right spot? Any thoughts?
