    I’ve done aboutn10 pair. Those made at HOLT are excellent
    Those made at Hartford appear less so. Not sure why.

    Time will tell.

    Hartford has no surfacing or coating in-house any longer. They're only doing finish work.

    Can anyone compare it to Hoya Ex3 and Zeiss Dura Platiumin? Both are excellent coatings.
