Watching a lot of the matchplay on Xtraframe, the Arena bay hooks about an arrow more than the main bay. Listening to Tim Mack commentate, he has said whatever ball you use to qualify in the Main bay, don't even bother bringing to the Arena. The lanes in the Arena are the old System 2000 synthetics... from the mid 80's!
After watching the Elimination Sweeper the other night, the Scorpion plays nothing like it did last year. Throw it right, and I saw guys get 3... throw it left... runaway Brooklyn.
I urge everyone to sign up to Xtraframe if you have a half decent connection (1500kbps). With the stuff that is shown, it is well worth the cost.
