Balls and more balls

Depending on how you strike the ball and if you try to control your spin determines your ball selection. Balls do spin more or go farther and all that jazz but you have to sacrifice one fire the other or find one that fits your style of play. I'm just now trying to spin the ball on all my approach and chip shots so I've switched to a proV1. In contrast, the prov1x has a little more distance to it with a little less spin. Id love to hit a ball that's as hard as a rock off the tee to get the most distance and then switch to a spinning ball from 180 in but that's not legal. So it's all IMO about how you want to play and if you have the ability to spin a ball at all. If not, stick with a cheaper ball because you won't notice a huge difference in your game just because you're playing a more expensive ball.

Superplumber,

It really depends on what will fit your game.  Start by looking at what are your biggest problems.  If you stay constantly in the rough/trees/etc. off the tee, maybe a ball w/ less/reduced sidespin is your calling.  If you hit is straight but lack distance (causing abnormally long second/third shots), maybe a distance ball is the answer.  Once you decided you worst shortcomings (that a ball can actually affect), go by a store or course with a good pro.  He should be able to help in the selection.  Or do what I do so much of...Google it.
