At the start of the round I use a New ProV1. I use it for 18 holes unless I get a scuff mark on the ball. After the round I throw the ball into my shagg bag, so when I practice I use the balls I would be using on the course to get the same feel.

I play the PROV 1 X until it looks like its been hit by a bus. Then I usually throw in the bag and use it for practice

I play the ProV1. I usually play with the same ball until scuff up by the cart path or the water gets in the way and claims the best ball I have ever played.

I play Pro V1 to start, if I lose or scuff that I usually swap it out for the NXT Tour Soft. After that, I will use a used ball in my bag.

Pro v1x they work fantastic as long as you don't lose them they stay firm all through the round round after round

New round = new ball

Pro V1x - Usually play it until it starts showing scuffs (I hate looking down at a marked up ball) or if I need scuba gear to hit the next shot. My "scuffy's" usually get tossed onto the practice green or into the practice net

It's very rare that I damage a Titleist ball before loosing it during play. I think the usable life of a ball is for as long as you can find it!

I use them until I lose them

I put into play a new ProV every 3rd round unless I lose one before then.

I average 6 to 7 rounds.If its a extra good golf ball i'll get 12 to 14 rounds out of it. I Like'm when they look like an old piLLow. awsome for short game I'v spilt three pro v 1's with a 2 iron in the last 3 years . Also pro v's have feel and sound that I love for putting.

I play the NXT Tour and the Pro V1. I play them as long as I can. Usually until I loose it or scuff badly.

Pro Vx one ball one round! After the round I usually just give the ball away to the cart guys or leave it on the putting green or toss it on the range. One and done!

I play the ProV1 (not the "x") and I often play the same ball for 3-4 rounds. I always carry two in my pocket (different #s) and will alternate on different holes (unless I get a birdie, in which case I will ride the good mojo).

Naturally, if a ball gets a cart-path scuff or hits a pine tree and gets all sappy, I will bag it for another, but otherwise, they just keep on going, like the Energizer Bunny.

That's one reason why I think ProV1 is a much better value (even at $4+ a ball) than the premium offerings from TM and Cally, because the durability is far superior. Their balls are nice, but good luck finishing a round with one ball surviving.
