I finished up my testing this week as well and my results were similiar.  I found the titleist test ball launched a little lower but spun more than my current ball.  Feel of the putter was similar to the 2007 Pro V1x I usually play, but the test ball felt softer on full swings.  I was a couple yards longer with the new ball versus my Pro V1x.  My favorite aspect of the new ball was the increased spin in the mid and long irons;  I was able to stop my 3-iron dead on some pretty firm greens during my test.  I will be putting the new Pro V1 in the bag when it is released.   

I have finished my testing  too.  I didn't see much difference in length but I did see more spin, especially on mid irons.  I didn't like the way the ball balooned up on shots into the wind with mid irons.  The difference in feel was noticable and overall a very good ball IMHO. 

However, I can't find the link to provide my feedback.  Did they send me an e-mail with the link?  I seem to have deleted it if they did. --jerry

The prototype ball felt longer than the Pro V1 that I currently use. I also found the cover to be a bit more durable. I had a 5 iron hit 3 inches from the cup and spin back 12 feet. Great feel around the green and off the putter.
