NOT! And the reason they never did or never will is because then you cant have a sanctioned league in that house. No sanctioned league means no sanction fees, no sanction fees means no money for the usbc. Revoking use of a ball cost them NOTHING...They actually (IMO) made some cash from this. See how this works? The usbc doesnt do whats good for the bowler, they do whats good for the usbc (their own pockets). IF they went around certifying every house I'm sure a few wouldnt pass BUT what a shock...100% of the houses passed! Back to the Jackals...I'm sure every ball thats made that is on the border of specs will have a certain number that will cross over that point BUT again...out of a million or so balls ONLY Motiv and Jackals were past the spec point? I find that hard to believe. If the usbc was really for the bowler, they would un certify some of these crappy houses, inspect the lanes and enforce some of their rules on the lanes. BUT this wont ever happen and it proves my point. Some people complain about the awards that are non existent...I dont care about the towel or key chains etc... BUT the beginner bowler or the 140 150 160 bowler that bowls 100 over avg or 75 over avg etc...get nothing. I'm talking about the Wednesday morning 11am bowler...The get nothing. A 60 or 70 year old bowler might actually appreciate the friggen towel or key chain...BUT that will cost the usbc money and it it cost them money, thats less money for them.
