There have been times that I've wished for a damper. I have a really good draft, even though the chimney is minimal, though straight up. I have got accustomed to using the stove a bit different than most to avoid over-firing. I never fully load the stove in the sense some do -- like filling up all the voids with small splits. On the other hand -- I like dropping my cleaning brush all the way through from the top -- a damper would just be another point to clean more or less by hand -- though the old Fisher damper never got in the way much.
Just go slow at first, learn your stove, & I think you'll be fine w/o a damper.
