Tough call. Many NOS PF's weren't installed for a reason and I've owned my share. Usually either ink flaws, chips in the edges or missing or mis-drilled holes. Had a Xenon missing the holes for one light by both slings.

CPR's are nice although the last couple I swapped I had them cleared again. Inserts could be felt under the clear. A recent FG actually cracked the clear around an insert. Still they are great and mostly available.

My personal choice would be a NOS, inserts corrected if needed, then cleared. But the supply has dwindled, so not much of an option as it was 20 years ago.
