I don't own or have access to other BJD, but from the ones I held, she felt about average.
I believe my girl is about 3-5 lbs. because she weighs about as much as a "dead weight" (ie. just got out of surgery and is still sedated) lighter cat. She feels about the same as my 6 lbs. tabby, but that's with my tabby wide awake and moving. I'm pretty confident that she weighs less than my tabby if I had to bear the full weight of my cat.
Hope that helps!
