This is not the first video I have seen of the client shooting from behind the PH. I would not follow any game in the bush without a solid plan. I can tell you that deer hunters loose their wisdom when driving deer from thickets.
My insight is to limit the the guns to PH and client, rehearse the client position, and firing order. Go over tracking wounded DG in camp before hunt. If client is weak, or shows indecision, then leave them back.
PH related story to me of client who fired on a lion, and then ran back to truck.
I want my PH to trust me, and I would stress that in spades before the hunt, and my dedication to his welfare, and that of the trackers is not doubted.
