Karl: In training tek divers, many instructors prefer air/EANx so they can assist a student with depth contol problems and have less bubble trouble concerns.
Walker: Why not teach fundamental buoyancy and trim controlling skills before you take a tek student to such depths?
Steve: Some divers might get freaked out at depth so it might be a good idea to take them down there on air first and have less bubble trouble concerns. You both have a good point though.
