Nice looking ball !
FWIW
I'm not sure if the rules are still the same or if your PSO told you, if you are throwing thumb-less the ball would have 2 balance holes and be Illegal. This was as of USBC may 2014

I am certainly not an expert on rules, but if you plan to bowl in competition it might be good to check it out, it might also apply to leagues but not sure if it does or if anyone would ever call you on it ....
