Barry,
The Ogre solid is a pretty strong little beastie with its stock 600 grit (US) surface. It is also extremely adjustable to be almost anything you want it to be. Stock, it probably fits at or just above the Gladiator solid in oil handling ability, but it flares less, so it won't have asmuch backend in stock form, as the Glad solid.
The Pink (Magenta) DC Warlock was stronger than the Purple. They have a strong mass bias so be careful how you drill them. Follow the directions. Both aslo flare a lot. It's more of a backend type of ball. Although it's sanded to 800 stock, the RG is high at 2.6. Like Lanemasters balls, hat high RG is needed to help clear the heads. It's probably a medium oil ball these days with what should be a HUGE backend.
