Davis there are alot of things to consider when choosing.  I currently do the same though.  It really depends on what type of spin and launch you like with your ball.  I plan on finding a Titleist fitter and get some numbers to see which fits me best.

There are so many variables, depending on your swing speed, ball flight, trajectory, spin, etc. that would make it hard to recommend a ball outright.

What I will say is you should get fit for a ball.  I just recently went to a Titleist ball fitting event and using a trackman they analyzed everything and recommended the ball that was right for me, the Pro V1x (which I was already playing.)

Check out the list of Titleist events in your general area and you will probably be able to find a ball fitting event pretty easily.  Good luck and keep hitting those greens.

Just to add to what Keith said, here's a link to current Golf Ball Fitting Events:

Good luck!

I agree wiTh the others that you should get fit.

However if that is going to be a while, head to the course with some of each ball, go through your bag top to bottom and look at a few different results, consistency of distance, consistency of dispersion, tradgectory, intended shot shape, and see which one performs the best for your game.
