I try to emulate SVB's break a little, and yes on my old phone I had the speed app and I was breaking between in the range 29/30/31. This particular night I had a couple beers and was feeling "loose" that's why my guess I was in the mid 30's. As I made contact with the cueball, it felt as though I was driving the butt through the shaft, it was crazy. I'm sure it broke because of a combination of the mini radial, natural flex in the shaft from striking the cueball, and less than perfect mechanics. Just wanted to share because it was crazy.
BTW my control 9 ball break is about 20-22 and control 8 ball break is about 24-25.
This particular night I was just trying to kill the ball.
