Nicanor,
Do you think that the ball needs to be clean? As you may know this ball soaks up the oil and I give mine a warm bath ever once in awhile. I have mine stacked and I love it.
I was not happy with the Cobalt Pearl, so not every ball is suited for everbody.
I have tried to play the G Force on the wrong lane condition and it did not do well. But when there is oil, look out!
