I'm actually really glad i bought a single tail wheel in the 7ft.  The dual tail wheel would have definitely been a problem in the woods for me.  with the single tail wheel i can actually swing it around and get the back of the deck very close to the trees as I'm working in an around the trees on my trails.  I probably would have swung a dual tail wheel into a tree already.  My property pretty much entirely sloped in one direction or the other but its generally fairly smooth with very few harsh transitions so i don't really encounter much scalping
