It all depends on your game. If you like an inside line, I do not recommend wasting the money. If you plan to try and play the outside line, then a strong ball is recommended. I have found my most success with a plished Pearl Reactive ball drilled pin high over bridge and Cg out for skid/snap. Espcially in the Doubles and Singles. I never needed a particle ball at Nats. A nice Solid Reactive Resin was the most I ever needed.
