When filling in forms or signing receipts, people hand you a pen they know works with their paper. Sometimes I use my pen anyway, and figure even with feathering my handwriting is probably better than most of what they get.

you could, but I don't know how much difference that'll make on Moleskine. I have an ultra-extra-fine nib with [[Noodler's X-Feather]] for crappy paper or just writing tiny.

I've heard some good things about Black n' Red paper, but I've never tried it myself. You may have to give it a go. The other option (which I'm not entirely sure is economically sustainable, but may be if you have a laser printer) is Printable Paper which you may be able to use in conjunction with this ivory paper or any other heavy weight paper.
