I recently rolled the Action.. with a 4 inch pin.. stacked leverage drill.  And a Action Packed with a 3.5 inch pin over the bridge, cg out to 4,oclock.

Action was really strong, recovering well... I played 28ish to 5ish.  The ball set up early but held and arc'd hard to the hole, carrying well, of a nice freshly oiled pair.

As the night went on, they dried out and I started throwing the Action Packed... I played up 15 and out to 4.. the ball went long and arc'd hard, and was not angular at all... it was absolutly the smoothest back end i have seen since the pulse.

These 2 balls will give you a good look on any house pattern from heavy to medium dry...

I am very very impressed with columbia's new line.
