The Helix could work for any style of bowler(even a full roller, although I've never seen it tried). The problem was know it all pro shop guys who didn't know how to drill it or didn't read the drilling instructions. It wasn't about matching your track up to the stripe. That ball had two pins, One small riser pin which located the top of the weightblock and a Black normal sized pin on the right side of the ball(for the RH version). With that Big Black pin, you were supposed to line it up on your PAP, then draw your midline and your track would line up perfectly with the stripe no matter how you tracked. It's a simple process for drilling that ball, it's just alot of people ignored it when drilling it and results came out funky.
