I got my SR2 last week and I absolutely love the reaction of this ball. Although I have only had the pleasure of using it once in one of my leagues, it was the 3rd game, I was able to string the front 7 before flagging a 10 pin, finished the game with a 253. As in my QZ1 post, I am just coming back from surgery that set me back almost 2 months. This is a modified stacked leverage layout. I'll be posting videos soon.
