The spines are surely too long for a crucigera subspecies. I have several crucigera ssp. tlalocii plants and a crucigera ssp. grandinosa and to my mind they do share similarities, but none have spines as long as this plant. To my mind it has more in common with haageana, just as your Lau 1106 plant, again because of the too long spines. But I do know just how variable plants can be in habitat, and I'd want to see both of these plants in flower before coming to a conclusion. The size, shape and position of the flowers would be helpful to distinguish further.
