I went with a basic label leverage drill, which is how almost all of my equipment is set up. The pin is under ring with the cg kicked out just a bit. Nothing too fancy, but workable. Oh, I did go with reverse pitch in the thumb, went with 1/4" where I had zero before. I noticed the back of my thumb had been getting beaten up and I wasn't coming out of the ball cleanly. It seemed to work out really well, and I think I may go even further reverse, as I had no problems dropping the ball at all.
At this point, the Doom seems VERY controllable, and that's exactly what I was hoping for. I've heard people say that it gets stronger as you put more games on it, too. Has that been the case for you, Chi?
