I threw the Vision at a ball demo this Summer and brought my Physix for comparison.  The layouts were kind of similar...Vision had the typical demo layout (pin over bridge, stacked) and my Physix was pin over ring w/ CG slightly kicked out.  Unless you went with totally opposite layouts, I believe they would overlap.

I answered my own question here.  I had to get a Vision, as it seems they are everywhere there must be something to them.  The Physix and Vision both have same layout and both have the box surface.  There is no comparison.

The Physix is earlier and smoother , where the Vision is longer and stronger.  I think they will both handle the same volumes, but the angle and shape are the main differences.  I was SHOCKED when I saw the Vision finally make its move.... its MASSIVE.   It has the Halo solid shape, just 15 feet further down the lane.

If the Physix cannot make the corner, the Vision wil do it with ease.  It's dramatic the difference between the 2 balls.

I want a Halo pearl now !!!
