These have been built for the BC xc team to practice on. Tight right hand turn after the drop is the difficult part! I have not ridden the largest one myself as all I can see is disaster! But I have seen quite a few attempt it some msking it look easy and effort less and some, well disaster and time to get the first aid kit out. Advice from those that can ride well (Rowan, Craig etc) seems to be to keep your speed right down, little more than walking speed and focus more on the turn than the drop. Best advice with a feature like this though I think is that if it looks a bit daunting make sure you can do the smaller drops perfectly every time before attempting the bigger one.
