Got intel from a Matetsi outfitter he has had 3 lions import approved. Will let him speak here if he feels warranted
If there have been hunters who have gotten approval. It might be good to ask for copies of the paperwork with the name redacted, or references of the individuals to verify they have gotten their lions back. You mention that you have already been burned once by an outfit at the Falls.
Be careful when hunting Matetsi. It is my understanding that there is at least one unit that is owned/controlled by an individual/company on the US State Department banned list. You probably don't want to commit a Lacey Act violation.
All the best.
