My MCP is drilled with the pin above and to the right of the ring finger, with the CG and MB stacked under with a weight hole. It's the actual ball that T.J. Trout used in the video on videoballreviews.com. While I don't throw as hard as T.J., I do appreciate the consistent reaction that I get from the MCP. I keep mine at 4000 grit abralon to even out the reaction. I use it when my Anarchy grabs too early in the back. I've shot several great scores with mine including a 300. If I was going to buy another one, I would probably put the MB in the thumb hole. That would be a good way to keep it from being too jumpy on the back and would be a good compliment to what I already have.
I've seen them selling on Ebay fairly cheap. It seems like a low risk investment regardless of the outcome.
