Hey mate - here's the deal with the move. It's more or less a small variation of Chris Kenner's Shifty, apparently created independently by Shigeo Futagawa as an alternative to Kenner's SWE Shifts in SW Elevator. The lecture notes are called, surprisingly enough, "Shigeo Futagawa's Lecture Notes" (lol), but I believe they're very hard to find. I found the move through a friend of mine, but as far as learning it goes, it's more or less just a slight modification of Shifty..
