The Conquerer is basically an Absolute Power designed for Heavy(+) oil. With liberal polish you can make it work on fresh medium, but it needs oil up front. As far as reaction, like I said - look at the Absolute Power to get an idea of how it plays. With the right amount of oil for the surface of the ball, it plays for me with a strong smooth arc.
As far as worth, if you have the oil, it's money. If you don't have the oil to use it, it's value is what someone else will pay for it who can use it.
