I love my Pro V1x - I haven't really tried the other models nor have I gone through a ball fitting.

I LOVE the feel and I also benfit from the lower spin off the driver and long irons.

I primarily use the ProV1x through the summer months, but switch to the ProV1 in the late Fall and Spring. I don't know if it is just me, but I feel like the ProV1 is a little softer to use when it is cold outside and the ProV1x is just the right density in the warmer weather. I like the way the ProV1x feels coming off the driver and the irons. It also has stopping power when the green conditions are right :)
I have never had a ball fitting, but I have been at Eagles Nest with Chris three times and each one of those fittings has been with ProV1x. I trust Chris and his expertise and I figure if he felt my ball speed and spin rate was not getting tuned in properly he would have told me that I should switch.
My AP1 fitting was done down south with the ProV1.

We did have plans to have a Titleist rep at our course in Barrie (Vespra Hills) one day last year, but unfortunately the individual ran into some issues and could not make it.

ProV1 for me! Best feel and performance.

I play the ProV1. It's so consistent. I know what to expect when I make a good swing/make good contact. I always pick up the Buy 3 Get 1 Free deal at the beginning of each season.

Pro V1x
Have played the X ever since it first came out in addition to the Pro V1.
The current X I was lucky enough to test and when I first hit it, was magic.
Current version Prov1X really matches my game even more than previous versions.

Pro V1x love the feel off of the club and it's performance off of the wedges. I have never had a ball fitting

Hi everyone! I play the Pro V1x exclusively now. I performed the Titleist Ball Fitting program (self fitting process) that Titleist used to have posted on the website. Surprisingly, I found that the PRO V1x performed best for my game. I had preferred the PRO V1 previously, but the performance of the PRO V1x was just that much better!

In winter months, I have switched to the NXT Tour S -- I like the soft feel in the colder months of December - March ...and it's easier on the wallet should it get lost due to lots of leaves, plugging, etc.

I tried to attend the local Titleist Ball Fittings out here, but they were oversubscribed! A testament to its popularity -- and I am talking about 2 - difference courses in which they were booked!

Mostly play ProV1x. I have played other Titleist balls, in the cooler months I play the yellow DT Solo(now the DT Trusoft).
I love the feel and distance from the ProV1x and the soft and visual from the yellow DT Solo. The Solo's still go a long way.

I have not had a ball fitting yet. For me, I'm happy with the performance of either of these balls. #1 ball on tour and in my bag.

I mostly play the ProV1x. I love the way it feels when putting. I will sometimes play a NXT Tour when the wind is up and I am not striking it the best.

I play the Pro V1. Love the feel of it. Love how it responds off the club face, and really love how it feels for the short game and off of the putter face. My Journey with Titleist started years ago with the Tour 100 balata, then switched to the Professional model when it came out, and then when the ProV1 came out I went to it and have stayed with it ever since. I tee up a brand new one at the start of every game!

I have played the ProV1x ever since it came out. I have done the fitting twice (Ontario & in Florida), and it confirms that it is the ball for me.

I play the Pro V1. What I like best is the consistent ball flight and how it feels, especially when putting. I have tried other balls but I just have not been able to duplicate the performance of the Pro V1.

I used to play Velocity most of the time but have now switched to ProV1 as I like the soft feel of the ball. I'd definitely like to try the new NXT Tour S to compare feel.

i've been playing last years NXT Tour S and then went to the PRO V1x until the new NXT Tour S was available here.

i'm loving the new NXT Tour S, especially in yellow

It feels longer off the tee and is giving me good control in chipping around the green. More one putts and less three putts

I play prov1x I was fitted and needed the x for lower spin numbers!

Currently I'm playing the prov1x.

It started in junior golf in 2001 when there was big hype of a strange new ball titleist released called the prov1 , Pros were hyping it like it was from another planet and I remember having to call pro shops just to be able to buy a sleeve. I put it to play in a junior tournament and the ball was extraordinary.

A couple years later the prov1* came out and that was my ball until the prov1x was released and has been my ball ever since. I love the firmer feel on longer shots and that little bit of clicky feel on the shorter shots.

The 2015 version is by far the best so far! Looking forward to testing the 2017 version when it becomes available !!!!

I primarily use ProV1X as my go to all around game ball. However my wife had purchased me a dozen NXT Tour S for my birthday. I was hesitant at first but now I find myself hitting better. Putting has also improved.
