This guy's threads o_O
Is he for real?
Anyway, you know which ball is yours because most likely the holes in the ball that isn't yours will be quite diffrent
And if you still struggle with finding your ball, get your PSO to give you colored holes. On my Grudge and Freak Show I have green thumbholes.
It was what the PSO had, didn't choose them because I struggle with finding my balls. My fingers are much smaller smaller than most I bowl with.
