Hello, my name is Jared. I am a right-handed bowler with medium speed. My right shoulder is lined up with the head pin. I release in a way that the ball rolls between the second and first arrow and heads to the pocket. I'm currently throwing a Virtual Energy. I can use the Energy when the lanes are oily, medium, or dry. I love the ball so much!!! I'm thinking about getting a C-System 3.5 but before I purchase it, I was wondering if you could tell me which ball is stronger, which has the longest length, strongest backend, etc? Thank you so much for your time.
