Jim,
I've dug out my two Left Homing machines and am piecing with them using both the wider ZZ foot and the narrower SS foot. I'm taking pics too. If there's any interest I'll try to put all this into a picture thread.
So far though I'm having zero problems. I guess even though I can't do it I'm doing it anyway.
I'll try some FMQ also since they both drop their feed dogs.
Joe
