This traverse uses most of the attractive feature on the back side of the SPAM boulder. The holds are big and fun, and the holds are textured and rounded. It's great until you get to the end, and then there's sand everywhere, and you have to climb through this awkward choss traverse. If you can figure out a way to start on this, and finish somewhere else, I would recommend that.
Back side of SPAM boulder. Start seated on the left side of the overhanging face, using pretty good holds. Work up and right across the big holds and rails, until you come to the vert topout at the end. You'll be a foot or so off the ground when you're finishing, so you can actually just brush those holds before you start.
3 pads would probably span the whole problem

This problem is described differently in different sources. The description here is as in the Caldiero guide. Personally, I think that described this way, the route is about V3. Good jugs all the way across. In the Bigwood, Grijalva, Pegg guide, Stumblebum Traverse starts further left, at the base of Joe Cool. This adds several difficult moves, and is quite a bit harder; probably V5.
