Here are some of the drawing pad and paper that I use as a canvas for the graphite/charcoal drawings.
I mainly use them for quick sketch commissioned drawings. From what I have experienced,they are intended for a not so detailed artworks who can be finished within just a few hours.
This is the paper that I mainly use for commissioned drawings that requires a lot of details and longer working hours. They are thick and has a good texture for creating a great tonal values. Unfortunately, though, I run out of canson ca.grain and I have only left with canson mi-teintes. It is still not a problem though since i can just go a local artwork store to buy another sheet of paper.
For more in-depth review of the paper, here are the links.
