Thanks Jeff and Riggs for your input. Your eyes are trained better to see these things and it helps some of out who are still learning these tools.

My input on the Shift is it is unbelievable for my game on walled up house patterns. I use it the minute I can start and wheel (in my case, it may be a tricycle wheel) to the dry. The ball gets the corner and just splinters the rack. I have to pick my spots on tougher patterns. The minute I see what looks to be some area develop inside of my target, this ball comes out of the bag. I also have a release where I just try to keep my thumb up and let the ball roll off my fingers and this ball will work once in awhile doing that. It can be a little too strong on the back if I am close to the friction line.
