I have switched to a thinner, ProGrips, gel grip. I find the opposite problem, i.e., that I need a thinner or skinnier grip as I have small hands. The fatter the grip, the more it tends to hold my hand in the open position and put pressure on a nerve right in the saddle between my right thumb and index finger. But, a thinner grip actually allows me to close my hand more and puts less pressure on that numbing area. At least this is what works for me.
