Agreed. I don't think anyone likes bleedthrough very much. It used to be that bleedthrough was a problem, but in my experience the newer note-books don't have the problem anymore. I have to think that the negative examples we are seeing here are examples of old stock. I am sure there are some inventories that still contain the Master 1917's with the poorer quality paper. Perhaps if one buys from a dealer that sells great quantities of stuff those inventories will no longer exist.
Having said that, I know there are ink and nib combinations that act very aggressively on any paper, so one has to experiment with various combos on one of the back pages that are perforated for tearing out easily. This way you can save messing up your note-book. Or better still, leave the page there so you can check in the future to see which combinations were no-no's.
