These are all overseas balls made for a distributor in Taiwan. Due to exclusivity rights these will not be sold in the US. Additionally, these are only being made in 11lb for the "spinner" technique.

Hope this helps!

The WTBA approved ball list is the same as the USBC one, so once a ball is USBC approved it can be used in any sanctioned tournament world wide.

Can't answer that, just reported what Ryan wrote over at BBE

What benefit, if any, does a strong cover/core give you with a spinner release where you are counting on deflection for carry?

I asked Ryan about this and here is what his response was, "they all (the balls) use lightweight and therefore less dynamic cores than heavy weight ball.  "Spinner" technique bowlers prefer a different cover strengths depending but almost always prefer a sanded finish.  So, our lightweight balls will generally have what "hook" bowlers would regard as lower flare cores and medium strength covers with surface."

Interesting.  Thanks for the info.
