I did my second and third runs on the Upper this weekend, what an awesome river.  From what I could see from the approach eddy above F-Up Falls most people took the left line cutting left of the top rock (pointed rock maybe a foot out the water).  My buddy/guide took us to the right, he said the right line was may a little harder but it keeps you away from tombstone.  

Question; is there two lines left of the pointed rock at the top of F-Up Falls, one that is away from the undercut and the second that takes close to tombstone.  Or if you go left you are taking a chance with tombstone?
