I have an old BX23.
I travel a bit to a sloped, wooded yard rental house.
I run through the woods like it's nothing.
I can steer around low obstacles, I cannot change the slope.
I always appreciate the lowness, and low center of gravity of the BX.
At worst, with a mounted backhoe I can swing weight left or right, and stabilize myself.
Having owned it for, say 10 years, my number 1 concern would be ease of mounting implements - even just the standard ones.
Sometimes mounting (say from dirt base) knocks me off my whole day plan...
