Within the past two weeks i have purchased a sigma hybrid which has been working ok for me. However i have had issues with transitioning to the third game, sometimes second depending on other bowlers. I just purchased the primal scream as well. I have not thrown the ball yet, but am looking for pointers and or advice. The house i bowl at is a 41 foot pattern, which is pretty much flooded in the middle and bone dry on outsides. i dont quite know what would be a better choice to start with.

Im currently thinking to start with the sigma and then when i notice it starting to fry and hook early to possibly change to the primal scream to get the ball to hook much later, any thoughts and or advice? thanks alot.

We would need some more information about your style.

Ball Speed
Revs
Ball layout(s)

ok sorry for the delay,

ball speed is approx 17-18mph
revs around 415 possibly more. not to sure to be honest

also for the layouts all i know if that the sigma pin to pap is 4.5 and the primal is 5. never really looked into the actual layout.

everything i get punched out for me my pro shop does it and i trust them to know how to do it for my style and shot .
