I hear over and over on other forums that the so called Strong Grip should not be used. Arguments are you can not control your clubface with the various hinging actions and the loss of # 3 power accumalator is significant in distance.
I argue for some people it is a good grip because it avoids the complexities of the roll to the plane on the back swing and the cock and unroll on the forward swing. I feel it is easier to avoid the dreaded club head flip. As for loss in distance there are just too many long distance(less #3 accumulator) golfers that had strong grips that just does not hold water (daly,couples,duval etc.). It is also easier to square the clubface. Also the pros with strong grips can work the ball as good as any of their peers with neutral grips.
My geralization is that it is not necessarily the best for everyone but for some (seniors,juniors, beginners) it can simplify learning the golf swing and playing the game at a adequate level in shorter period of time.
I am interested in the pros and cons of what I have said since a number of instructors encounter a slicer with a neutral grip. They then will work with that player numerous years and never correct the slice.When the instructors are not around I have them strengthen their grip and have them hitting a draw or straight shot in 5 minutes and their distance increases as well.
