Amazing trail. You can really pick up speed quick on this one. Defintely keep yourself controled. Took a super hard crash on this one once because I felt comfortable and just kept picking up speed before a root took me for a ride. Techy at the top with some amazing flow in the middle. Love the ending with the double drop.
