Yes, unusually tight center holes are difficult to find in our hobby...Congratulations.
HOT Stamper...Im a believer ....
I recently picked up a mint copy of YES Fragile...immaculate cover, clean, virtually unplayed vinyl...and two indicators that this was a special pressing...the center hole was unusually tight....and the outer rim of the lp was very sharp...as if straight off the lacquer...and the sound...is truly breathtaking in a full 3d way... price: 5 bones!
