I have talked to brunswick about the ball, it is identical to the OI. And as far as can't be used I dont see why not, if someone wants it just for the signatures or whatever then so be it, otherwise just drill it, the signatures would wear off in no time... not a big deal. Also as far as not being special, there were fewer of the PBA version made than the OI... it is a rare ball. And for 150 shipped on any new ball is pretty reasonable.
If someone wants it for 100 then I might consider it, but they pay shipping.
