balls size

[cdballs]

i guess the average i 5x2x3 length width height in cm mine are 6.4x3.8x3.8 and they do a calculation to get volume by doing 6.4x3.8x3.8x.52=48 and the average volume is 18 to 30 so are my balls huge, big or jsut above average jw cause i never thought they were more than normal.

does ball size matter in busting is bigger better or what ?
do sertain sizes work better for sertain busting ?
girls?
