It's not up to the individual instructor. If PADI say teach the eRDPML, then that's what should get taught.
Bear in mind tho', that it's also down to the instructor to make sure you both have the correct materials, as it will be their aris on the line if PADI finds out......
1. There is a provision that allows instructors/schools to use up their existing stocks of Wheel or eRDP before changing over to the eRDPml.
2. Again, get the instructor to confirm with PADI about this definition of possession when it applies to couples.
