I love mine. It is drilled 3 3/4x4. Awesome controll ball. I have never had nor have I expected to throw a pearl ball of any kind (reactive or particle) be so predictable.
The hit at the pins is great, it gets down the lane cleanly. The only time it over reacts is if I get it out into the dry too soon. It does a get a little squirty on oil, but with my ball speed 20mph+ it still ends up only being about 2 boards adjustment to work. With that said it should not be as squirty for someone with slower ball speeds.
Great ball, I would pay high performance price for this thing.
