I used to bowl in leagues when I was younger. Now I go about once a year. Average around 180.
I weigh 140 and use a 12-14 lb ball. My style is very unorthodox but it works when my aim is on point. No spin, pure power (i do a little jump before i release, my friends make fun of me), right side approach from the start, aim for 1-3. When I strike, the pins fucking explode
