I've slowly gone up in grip size over the last 10 years or so -- from standard to the now sadly discontinued Diamond Tour Super Jumbo (or whatever they were called) grips. I just find it easier to hold onto -- less grip pressure. My hands aren't that large -- used to wear a ML Cadet glove. Some who like the fatter grips point out that in no other "stick and ball" sport is the handle anywhere near as small as a standard golf grip. Racquet sports, baseball, hockey, even polo grips are larger.
