I'm currently a lefty bowler 16 mph, avergae revs. I stay behind the ball , a tweener , and my go to ball is a Playmaker. On THS my playmaker is my hardest hitting ball. I plan to start shooting on a few pro shots and need something more aggressive . The options I'm considering are - Pure Swing , Mutant Cell , Jigsaw Corner ,Total Bedlam or Invasion. Any input on which of these balls would be well suited for me. I like to play up 10 to my breakpoint being 5 and want an aggressive backend ball.
