Working in a golf shop makes it possible for me to get my hands on and play most of the balls on that list. I am always looking for a better ball. In the past year I have played at least 9 holes with Titleist ProV1/x, Srixon Z-Star, TaylorMade Penta TP5, Nike 20XI, Bridgestone B330 and E5, and Callaway HEX Black Tour. For me the Titleist ProV1 and ProV1x are the best. The ProV1/x has all the aspects I want in a golf ball. I play the x during the spring, summer, and fall and the ProV1 in the winter due to the firmer conditions.
Here are some of my thoughts on why the other balls don't match up IMHO:
Srixon Z-Star- Feels too firm in the short game, not enough greenside spin and control
TaylorMade Penta TP5- Playability on par with Titleist but durability is a huge issue
Callaway HEX Black Tour- Same as The Taylormade, good playability but only lasts about 9 holes
Nike 20XI- Nike has never made a good ball in my opinion, feels way too firm in the short game yet spins way too much off the short irons
Bridgestone B330 and E5: Much to firm in the short game the E5 feels like a rock.
These are just my opinions and other people I am sure will disagree. The only 3 balls I would even consider playing competitively are the Titleist, TaylorMade, and Callaway. The problems with the last two are I have to change balls in the middle of a round. I can easily get 18 holes and more on a Titleist and since I am not made of money that is important.
