Hi. I have 2 thunderclouds. I am trying to determine my proper grip size. One fits me perfectly, the other is slightly large. One says 4, the other says 5. The size 5 is a "Shock Eraser" grip, the 4 is normal. Now I am worried because my S2 which clearly says 4 5/8 (thus far too large) is bigger than the size 5 prince. All I want to know is the size of the smaller thundercloud so I know what to get when shopping for my warrior or whatever I get. So is the prince size 4 really a size 4, or something else?
