I've never been to a club that uses Pro V1 range balls but my old home course used Nike RZN non-range balls. Every range is different, my current course uses range limited balls because the back of the range opens up to the course and a 300+ yard drive could hit someone. I've been to other ranges where they use range balls without distance limitations.
Best thing is to ask the range workers what type of range balls they use if you want accurate distances. I sometimes bring shag bag balls to the range that I won't use during a round and hit them to get a better idea of my distance with new clubs.
golfers are puling out most certainly because they dont comply to anti drug rules of the olympics. this is new matter to deal with for golfers. golf standards and controls are much lower on the ET or PGA versus the olympics.
the zika virus has a good back to support this withdraw communication.
end of story. in 4 years drugs will be in "olympic" control and more players will come.
it's obvious that the "gym" fitter golfers like mcilroy withdrew very very fast.
Without having the strokes gained stat, it is difficult to tell how good Lydia is compare to others. But whenever she's within 10 feet, I feel like she is going to make the putt and she often does. I think she is one of the top 5 putters in LPGA.
As for Julie Yang, her GIR stat is one of the worst in LPGA and she may be hitting a lot of 3rd shot (on par 4) into green, close to the hole. I don't know much more than that about her game as she rarely makes cut.
