I am a full roller. I used to bowl with a columbia messenger tec, but encountered someheavy oil. I needed something new. I went with the Big one. Originally got it drilled with pin by thumb. This didn't work for me. I eventually got it plugged and redrilled with a reverse block. Now, it works great. I have also since bought a black widow which I also had drilled like the big one. They work great for me. I went and worked with my pro shop to get the drilling right, and once we got it, it works great. I have also thrown a no mercy and it also works well.
