When you use the long edge it breaks your wrist structure, I think it would be a lot more effective to use the short edge, as it could be used to retreat to ochs or pflug if needed.
To my experience the Schaitler works best (along with all the other Hutenbrechen), when the opponent is about to go into the Alber guard. Indes, man, catch him BEFORE he resumes the guard. When he's already in Alber, your strike is most likely displaced by a Krump.
Actually, I tried it out, from curiosities sake and, not only would using the false edge rather than the true leave him in a stronger wrist position, it actually seems to give a hair more reach, like I can extend the point of my sword slightly more while still being comfortable, if I turn the sword to use the false edge instead of the true.
