I play the Pro V1x. I am left-handed and usually hit the ball higher than most people. For me, the Pro V1x gives me the perfect spin off the driver and long irons and is great around the greens. I haven't tried the latest Pro V1 but I am going to next Wednesday. I will only play the Pro V1 or Pro V1x. If it is good enough for the majority of the best golfers in the world, then it is certainly good enough for me (8 hdcp).

You should check out the blog post from the R&D about the new golf balls. They talk about the myth of needing a higher swing speed for the Pro V's. I do not have a high swing speed but of all the balls I have played, the Pro V1x has been the best for my game.

Hope that helps!

Pro V.  Best ball in golf.

For a more detailed answer: I would say that the Pro V gives me the best result around the green and on half shots (wedges and irons).  The B330 is a good ball, but the Pro V is better for my game.  I've never been fit for a ball on a launch monitor, but I've used them both for a couple of rounds and the Pro V gives me what I want around the geens.  I'm not long off the tee so the greens is where I make up for it.
