I had a playable line to the pocket last year on both shots with a Gamebreaker 2, with a 2" pin to PAP, no hole. It stabilized in the fronts like urethane and gave me a little more motion on the backend than urethane. I missed just about every single spare that wasn't in the middle of the lane though. But that was my best look.
From all of the reports this year, I'm hearing that they're a bit tighter and the people who had the best success played off of their reaction at the end of the pattern, rather than trying to get the ball started up early.
They're going to be hard no matter what, put your shot maker shoes on with your spare game soles. There's no way to "trick it".
