sandermarijn, it was you I was referring to in my post as I had spotted in a search that you had used MGII filters with later MG paper successfully as you have confirmed.

I think you are saying that your old MGII filters are in fact producing exactly the same grades as your new MGIV set? Maybe they haven't yet faded.

As I said in my above post my MGII filters seem to show little use as well but I have yet to test them
