When I was in university (Mechanical Engineering) I had 2 types of writing stick/paper combinations - for homework and for taking notes. Homework was mechanical pencil and graph/engineering paper. (Engineering paper usually has a border around the grid and some sort of "title block" area. It was the standard in my department.) Taking notes I used copy paper and a rollerball pen. The copy paper was thick enough to prevent the ink from smearing or flowing, and it was completely blank - letting me draw sketches and FBDs anywhere I wanted. Since most of my classes were math-based, with lots of little pictures, this worked really well. Punch holes in it, and stick it in your binder, and less expensive than most other decent paper. ... BTW, my rollerball pen was capless, similar to this one.
