A lot us used to descend the next couloir north. It has a big boulder at the bottom that is negotiated by sliding down its right side. Picture of it from the main trail, looking up (the big boulder is below and to the right of center):

Nowadays, my friends and I prefer the southeast couloir, the main advantage being that you hit the main trail a few hundred feet higher.

Your number guess is close. Here are the routes I have done, with the dark green one being the latest. Some of them have names, official and unofficial, starting with the one initiating near UBSL and going clockwise:
Dark red, Smiley Face
Dirty gray, Secret Route
Blue, usual east couloir descent route
Red-orange, southeast couloir (two different starts)
Dark purple, Stemwinder
Salmon, Satan's Delight

Certainly there are more possibilities. By way of Wotans Throne, for example, and the way labgloves did it (saw your tracks clearly on Monday).
