Ok I am just a league bowler. I bowl once a week. I have had a hard 3 mo. since brunswick bought the house I bowl at. I decided to make a change. I bought the Virtual Gravity after doing some homework. I love this ball. Took me about 2 wks to get used to it. Last 2 games were a 224 and a 268 that should have been a 300 but I got lazy in the 5th and threw a split. This ball rolls long and breaks hard. It has some forgiveness for heavy and light hits. I highly recomend this ball with lanes that have a typical house patern and moderate to heavy oil.
