New line on Upside Boulder

Ian Cotter-Brown has reported a new line that traverses from left to right on the Upside Boulder before topping out. This boulder, which is located up past the Saigon Boulder about 200 yards or so, is newly included in the 2nd edition of the guide (page 299). The problem begins to left of the west face down low on a good hold and moves low right to top out on  Early Exit (a v5 mentioned in the guide). The traverse could also potentially be linked into Upside (v8) to give a harder link. The problem done is somewhere around v8-v10, but needs confirmation.
