Having a golf ball that suits your game is probably the most important piece of equipment. The reason that I believe this is that it would not matter what kind of clubs and shaft's you use, if the ball doesn't suit your game it will only cost you shot's around the golf course. Even if it is only one shot a round, that adds up to 4 in a tournament. Therefore I will not use anything that I believe that will stand in my way. 

I use the Callaway ix Tour because of the feel that it gives me. The ability to hit the punch shot in the wind with consistency that I require. The feel around the greens is outstanding, you can hit a spinning chip shot with ease. And the length off the tee helps as well. Since switching to the Callaway ix Tour my driving accuracy has improved and I believe my overall game has improved. Hopefully I can put it all together next year.
