In my 28 years of teaching students of all levels, I have found that making the
needed adjustments concerning grip type and grip size gives you the best chance
of realizing improvement very quickly. If the grip is too small and slippery, you will
tend to hold on much too tight, creating a host of swing problems.
If using what are considered standard size grips by most manufacturers, chances
are their grips are too small.
Be on the lookout for this ongoing potential for trouble.
