This is a 15-pound Prime Time S. I received it from Pro Takada, but I've had fewer opportunities to bowl, so I'm offering it for sale in hopes that someone else can use it. I haven't thrown it at all since receiving it. The pro also didn't throw it much, so I think it's in good condition. The drilling has three holes: two for fingers and one for the thumb, which is IT. There are no plugs. This ball was used by many pros in tournaments, so I think it's quite easy to use. It's a solid ball, but it's polished, so the ball motion is easy to see, and I think it will be useful in difficult lane conditions or conditions where you can easily feel the lane's transition.
