I just added the page for the SE spur.
Concerning the section "routes" in your page I suggest that you add the W-ridge. This is the normal route, and most often used for the descend.
further there are numerous routes in the north face, but I don't know if it is useful to mention them. however, the south ridge is important to mention, since this is also a possibility for descent (into the other valley), and often used when traversing mt collon.
there is also an additional spur on the south east face (grade D+) that I cannot remember the name of.
