I also define "stronger" as how much oil a ball will handle. My Mean Greenie will cover more boards than ANY ball in my arsenal on the right conditions, but it's well behind the Violet and Granite as far as "strength" goes. I ask about the Ogre Pearl only because last year I had an Ogre Solid @ 600 grit and the ball covered as many boards as my Slate Blue does. Couldn't swing it not matter what, only success I ever had with it was playing it up 5. I traded for it used, so maybe it was dead when I got it, but rather than put any more money into it to re-drill I just got rid of it. Ogre Pearl will be drilled a bit stronger and cover left in OOB 1500 polished . Really hoping it is a step "above" the Violet as our house tends to put out alot of oil and would like something between the Granite and Violet. Thanks for the replies.
