Re: Neutral Grip vs Strong GripWhether the left wrist is arched or not is not a Weak/Strong factor to any great degree. I try to be neutral, and my left wrist is very arched at address.
The back of the glove facing generally forward toward the target is a neutral grip, and Hogan did that. A strong grip has the back of the left hand facing more toward the ball at address.
I think we still have a misunderstanding of terms here. Trevino said he used a strong grip, but only because it was slightly stronger than Hogan's, nothing like Azinger's, which really was strong. Trevino had the back of his left hand at impact facing down the line and slightly left of target and pushed the ball. If he had a truly strong grip, facing his left hand down the left side of the fairway would have hit the ball hand left.
Hogan was the gold standard and, as Icarus has essentially said, Hogan used a weaker grip than he advocated. Other players who were slightly stronger than Hogan tended to call their grips strong, but in relative terms. Compared to a true strong grip, which I freely admit many young players start out using today, most tour guys are within the range of what is commonly called a neutral grips with an arched grip. Anytime the butt of the club is under the heel pad, your wrist will arch or you will drop the hands well below a normal address.
I have seen many strong grips over the years. As players evolve and squaring the club becomes more natural in their swings, most (but of course not all) evolve to a more neutral grip. They may not get much higher than the right shoulder, but that depends on the hand size, finger length, how much in the fingers one holds the club, and the phase of the moon, for all I know. I am quite confident that it takes more control to play with a truly strong grip than something that fits into the range of a neutral grips. Most of us are not skilled enough to play with a strong grip and hold off shot after shot without hitting wild shots from time to time. It takes an amazing lower body to play with a strong grip, but it you can do it, fine -- you are very skilled at controlling the club.
Maybe we just agree to disagree, and have different definitions of what is strong and weak. Words are not nearly as good as seeing how someone actually grips a club. No big deal.
