Each diver, whether a DIR diver or not, makes choices about who they buddy up with. For some it's a considered choice and for others it's a bit more haphazard.

Speaking personally I would buddy up with anyone to go "confined" [1] diving. Depending on a number of things, I'd want them to be comfortable with me and vice versa. So with a non GUE trained diver, I'd want to be sure skills and procedures were compatible, so more discussion ahead of the dive and perhaps a shallow skills dive to cement that.

For cave diving and deeper trimix diving I'd only go with DIR buddies.
