What's the best sticky note for studying and annotating books?

For annotation, shoppers gravitate to transparent notes that let you write over text without hiding it, and to lined 4x6 pads that give more writing room. In this pool the Post-it Transparent Notes and the Mr. Pen transparent tab set both target this use, while lined options from HQCME and Post-it Greener Notes suit longer notes. Transparent notes generally require a ballpoint or permanent-style pen rather than a standard gel pen.
