Resurrecting this thread - J_Mac, how does this ball react for you? Did you ever come to a conclusion on what this ball is? Just got one myself that I'm going to drill up on Saturday, and was just curious what to expect. I'm going to drill pin under ring finger, kicked out slightly, with the cg kicked out a few inches.
The ball I have looks exactly like the one in your pic, and from what I've seen, looks most like a Jekyl to me.
Thanks,
Jeromie
