The Intellect was good for me at box finish, but it was actually a bit too strong on the backend. I don't know if I've ever had a solid that can turn on the back the way that one does. Nevertheless, I took mine to around 1000 abralon, and now it is my oil ball for tourneys. It picks up a lot earlier than it did when polished, and the move on the back, while still plenty strong, is much smoother and goes through the pins better. I think a lot of people missed out on the Intellect. It's a fantastic ball!
