I'm not totally sure what versions are in the PiF although I would take a guess at the single layer versions. Ideally, I would like the dual layer versions, but this set seems so hard to come by that I'll be grateful for anything. Late last year, I asked another member here (who had the dual layer versions) if he could send me copies of the dual layer set, and to save me some money my end, I said I could send him the blank dual layer discs for him to burn the copies on to. He agreed to this on the condition that I send him an extra three blank dual layer discs. I don't think that was very cost effective for me, and someone was possibly taking liberties from the whole situation. I never got the chance to seal that deal as soon after, my net connection died for two weeks and then the Buncefield disaster blew my PC up

Wow! I went on a major ramble there, sorry.
