I use this paper for everything 20# paper can be expected to do--from printing recipes from foodie internet sites to preparing camera-ready documents for Staples' printing geniuses to process for my non-profit group's newsletter. Our penny saved is a penny appreciated these days.
I'm an architect. I make 98% of my drawings on 11 x 17 sheets. My procedure is to make the first drawing on 11 x 17 vellum. Then I make 11 x 17 copies of the base drawing to use for the different construction disciplines: structural HVAC plumbing and electrical. Starting with one drawing I have 5 typically. Since I use drafting pencils in my work I wish that the copy paper had "tooth" equal to that of vellum but the convenience of using common copy bases overrides my irritation with the pencil line work feel.
