I have all sorts of paper in my cabinet, but really only use bristol board for my drawings.  Of course I sketch in any available sketch book, but a finished piece is done on bristol.  I'm down to my last few sheets, so I decided to visit Utrecht and stock up.   I use their house brand in either vellum finish or plate finish.   The subject determines if I use the smooth (plate) or textured (vellum) paper.  Dogs, for example, are easier to portray on a textured finish since it helps create the illusion of fur.  Glass is better on smooth.   But whatever the finish, it's good quality paper at a great price.
