The Pro V1 is for a really serious golfer. Yes they are a good ball but it all depends on what you are looking for. You get a fair bit of spin off of the driver which isnt good for some people but u get a lot of feel around the greens and if you hit a good wedge shot the ball will rupe back towards you
I like the Pro V1 for cool days and the Pro V1x for warm days.
I keep trying other high-end balls, because prices are outrageous, but only the Callaway HX Tour is even close to the performance of the Pro V1.
But Rusty is right. They are not for everyone. If you hook or slice a lot, you will be happier with a lower spin ball. If you want pure distance, there are others that are just as long but a lot less expensive. If you have a slow swing speed, you will want a softer ball like the Noodle. On the other hand, if you have a strong swing and want very good distance with a good amount of spin and bite around the greens, there is nothing better.
Depends what you are looking for. You definatly don't get as much distance with them but I have never hit a ball that spun that much for me. The pro V1 x is a better choice if you are looking for a bit more distance but a little more sacrafice in spin. I'd only use them in a tournament or if moneys on the line though these things are expensive!
