I'm not an paper expert in any way or form, this is just some thoughts and experiences I have collected during the last 2-3 years.
There are three different things that you need to take into consideration when you are looking for a new notebook, and more specifically the paper in it. I usually look at it in the form of the following triad
- Thin paper
- Short dry time
- Little bleed through
It isn't hard to find thin paper with no bleed through, but it will take a while before the ink dries. And it isn't hard to find thick paper with short dry time and little bleed through.
There are exceptions to the rule. But my experience is that You need to pick two of the three.
