The main difficulty is traversing the loose rock and natural rock, with less lift it will make you pick wise lines to get around them with out dragging while you dodge hitting the tightening trees, at a few spots may require multi-point turns to snake between the many trees. Add in water collection spots, mud, off-camber spots, and rain, and the difficulty is right in between a 3/10 and 4/10.
