I’ve had a roll top for seven years now and like it. The first thing I did was convert my vise from clamp mounting to pedestal mount. Regarding size, I like one with drawers on both sides so this would be considered large. Also if you plan on closing it up, get one with a higher top in order to accommodate your vice height when closed. I also use a gray or white background board for contrast. Natural wood looks nice but offers little contrast when you’re tying.
Some of the more modern desks were meant to accommodate computer monitors. While nice, unless you plan on mounting a monitor or Ipad, this void is a waste of space. Regarding compartments, they will be small so don’t think you’re going to be storing fur, skins or feathers up top. Mine has very few drawers but lots of open compartments. These are great for storing things you may use often, (hooks, dubbing, glues), and they will be in plain sight.
My desk drawers house large plastic containers for skins, furs and hair. That said, I still have a small mountain next to the desk that contains feathers, beads and additional dubbing. I’ve attached some photos to give you an idea of my set up. Good Luck and let us know how you make out.
