Vincent, I had just heard some talk of the cup on the radio - maybe that is what made me notice the nets. =)
AgentX, I encourage you to do so, they are lovely little jewels in person. If you're making negs specifically for enlarging they might be a little thin/flat. Buy grade 3 and try it with your more dense/contrasty negatives. SOO easy to print with amidol and a water bath.
