Pro V1's from Titleist are fantastic golf balls, the best available but they're not the easiest to play with for beginners. They're both excellent for beginners, and difficult at the same time. Due to the high compression rating, you need a faster swing speed to get the most out of them, a faster swing speed can lead to trouble for a beginner. Its purely down to personal preference, they're relatively expensive, but if you're consistently getting better and more confident, the Pro V1 is an awesome upgrade.
