SORRY, After I thought about it, I figured out you meant CARRYDOWN. I don't use a different TYPE of ball, as much as a different drilling. I start with a pin down AWESOME REVS, then, when it WIGGLES,(DOESN'T DRIVE OR FLIP), I switch to a pin up-WILD THING. The pin under ball gets the ball moving with more midlane, and the pin up delays the hook, for the CARRYDOWN.
This works for ME. There are MUCH better instructors on this forum.
GOOD LUCK, the don
