Just tried out the zero gravity the other night.

Drilled pin in middle finger, mb kicked out to the left a bit.

Specs:
Avg: 222
Mph (at pins): 17.9
Rpm: 390
Pap: 3 3/8, 1/8 up
Tilt: 11°

I had heard mixed reviews about this ball, and I deff prefer symmetrical equipment (as a lefty who rarely moves his feet) but for $30, I figured I'd give it a go.

What I saw:
This thing wants to grab the lane the moment it leaves my hands.

Would get through the heads ok(primarily bc my ball speed), but after that came mid lane read that didn't quit until exiting the pin deck. A smooth arch from like 35' til the end. I was surprised to see that it still had energy to take out the corner. Man is this thing strong! Tried many angles/lines and no matter what, back to the pocket it went with a pop!

I could see how folks would have been disappointed as it doesn't have that snappy back end finish folks have learned to love. But that has never been my style. As a few have said, I find it to be my iq tour solid on steroids.

Loving the smooth predictable and strong motion. Only dislike is that with the strong core (as ive noticed with most asyms) the ball I can't seem to manipulate the motion with hand changes.  It's as if the motion is "built in"

You must bowl on really dry lanes . . the Zero hooks for sure, but is by no means a hook monster.  The core is also not very strong, rg of 2.55 and a diff of .037, that's average or "medium" at best.  It's got to have some odd surface or the lanes you were bowling on had to have been burnt up, every one that I've seen looks like a stronger Hyroad Solid, which still isn't saying much because that ball isn't very strong either. 

Avabob nailed it. The Zero is a versatile piece for many bowlers.

The reason is that too many of the hook monsters burn off their energy too early for most styles.     

+1

The Zero Gravity makes a great choice on various shots.  I've used it with success playing deeper on a THS and some of the longer WTBA patterns (Mexico City and London).  I would say the ball motion (as hockey stick-ish as a solid could get) makes it look like it hooks a ton since it saves it mostly for the backend...
