Jeremy, you can and I do myself.I have a smallish 16"er by New Braunsfeld(a precursor to the ones Horizon makes now-heavy) and a big Tejas.
I burn wood only(thus my name) and intend to use wood in my UDS when I finish her.
The trick is to get a small hot fire,feed it with wood when she starts to drop temp.I had some really good shots of my fires bvut a computer worm ate every thing.
My pieces are usually 3"X3"X8" or so and YES it is a lot more work,but worth it. Oh, when you put your wood in it should almost catch fire immediately.
Pre-heating the wood on top of your fire box helps too
The wood catching quicky helps in not getting the dreaded "white" smoke,and creating a nice blue,barely visible, wispy smoke ;remember , you don't have to see smoke to get the effect, if it smells like smoke it is doing what you want.
Hope this helps and always remember,
