I learned that when I started league bowling way back when. It worked great for me, giving me a predictable slight hook, about the width of the ball down the lane. I can drop the ball on a dot and it goes where I want it to. I bowl infrequently now, but it still works. I get fewer strikes without practice, but I’m picking up spares just as easily. Being right handed, its easier to pick up the pins on the left.
Before I start doing that, I had to roll it straight, or get a curve I had no control over.
