Titleist is a company that has been producing golf balls and equipment since 1932. They are known as being the number 1 ball in golf, and golfers all over the world use Titleist golf balls. Titleist ProV1 golf balls are very soft, and they are very good at stopping on a dime when hit onto the green. They are more easy to control than other golf balls. ProV1x, on the other hand, is still a very soft golf ball, but not quite as soft as the ProV1. The ProV1x is known for traveling a great distance, and is engineered for hitting the ball a long ways. Professionals all over the world use Titleist golf balls when playing in tournaments. There are 8,330 pros that use these golf balls. I would recommend buying some of these balls if you don't mind paying a pretty large amount for golf balls. They work great for amateurs as well as professionals.
