why is this..it was never as bad as it is now..juddering and tearing music...and some courses meter slide jumping and leaping in a very odd way. I,ve just come off a practice at St \andrews but it was perfectly fine...played earlier back 9 at Congressional and completely awful..meter was horrendous. Am not griping 4 the sake of it ..just would like to know if anything can be done ..from either end...ok ..thanks.
