I searched and no satisfactory result. Anybody uses this shuttle regularly? I read that it supposedly in the same range as victor tourney #1 (blue). Is this true? good enough for club play and regional/city tournament. I bought 1 tube for a review and it's still in shipment somewhere. If you guys are interested, I have a connection that can get it for $15/tube/dozen shipped to anywhere in north america and I think rest of the world. It'll be less for more than 5 tubes order, I think.
