i bowled the best in my life. at first it felt very weird and i didn't know how to throw it, but after a while i started throwing it the same as when i use 2 fingers accept it kept my wrist straiter, i was able to throw the ball way faster and hit my spots. and unlike with 2 fingers the ball didn't slip out or hook to much or not at all. infact i got way more hook and speed when i used three fingers, i am just thankful i found one on the free rack
