I have played ProV1 since it was introduced. Previously it was the Titleist Professional ball, the HP2(??) and before that we all played the PTS 90 and the guys with the fast swings went with the PTS 100. The 90 and 100 referred to the compression of the ball linked to how tightly wound the balls were. We even had a ladies ball that was a PTS 80.
All of this has long gone and I was told around 5 years ago by one of the marketing guys at Titleist that the PROV1 was around 88/91 compression and the X was around 96 compression, so I stuck with the lower compression. I am now 71 years of age and playing off a 6 handicap at Gullane Golf Club in East Lothian, Scotland. I believe that, with all the improvements in our equipment over the years, I still hit the ball as far as I did when I was a one handicapper at the age of 20. This, for me has extended my years of golfing pleasure, for which I am eternally grateful.
I found a perfect ProV1X recently and played with it yesterday and last Saturday in good weather conditions. I am really quite puzzled by the lack of perceived difference in the two balls. I was delighted with the ProV1X and have avoided using it in the past as I assumed that I would not get a result from it as my swing speed would cause me to lose distance. That has not happened and I just may have gained a couple of yards.
I was surprised to read that Henrik uses the ProV1 rather than the X and I asked a couple of Senior Pros recently at the Scottish Senior Open why they were playing ProV1 and not ProV1X as I expected. The answers that I got were spin rate. Spin rate seems to be the key to this question, but I am not convinced that a pensioner such as me, albeit with a 6 handicap, should be paying any attention to such a thing, if in fact, I can detect any differences in spin rate between the two balls.
Some sort of understandable input to this question would be welcomed as I am at a bit of a loss in coming to a conclusion re which ball to use!!!
Thanks in anticipation of a good, informative discussion,
