Why not go with the Virtual Gravity? Its a best of both worlds. That would be my choice.

Japaters,
If the Virtual Gravity is anything like his brother, Gravity Shift, then I'd wait to get it.  But If I had to decide between the Attitude or the Dimension, I have both, I personally would pick the Attitude because I just match up better with it.  But that's for me, it may not be for everyone else.

I have not had a chance to punch my V.G yet, but have thrown both the Dimension and Attitude quite a bit to hopefully add to this.

What I have seen from my Attitude was a ball that read the friction pretty strongly. My Dimension is strong, but in a different way as it is great all the way down the lane. My Attitude could scoot past the break if I goosed the speed a little too much, where the Dimension was hard to shoot past the spot.

I did try both of them shined and the Attitude was a lot more angular than the Dimension with shine.

To each his own. The majority of folks I seen throwing the Attitude used them shined and when a longer pattern started to burn in the front part of the lane.
