this thread inspired me to muck about with the current method i use (3cycle) and eliminate edge orientation from it completely. it wasn't hard either, as EO is so easy to manipulate. you just have to learn 4 associations (in one of which you do nothing). no new algs, just different (not harder!) setup moves
i'll practice it a bit and if it wasn't a waste of time, i'll see if i can do the same for CO (although to make it feasible, you'd have to memorize algs, about 8, else the setup moves get ridiculous)
