Good perspective and good hunting to you, if it wasn't for the two flights between you and home you'll come back the most relaxed you've ever been. I miss siting around a mopane wood fire with a Lion Lager or brandy something fierce right now. Dead of winter outside still and 59 degrees north in the bush.
This is the same as any social interaction, but once you figure your PH and if you decide you like him, just let him do his job and trust his judgement. I made clear my first trip to Zim I was there to experience it and if some animals came out of it, great. They went above and beyond to make it great as we struggled to find a Cape buff bull which was my focus, ended up with one day 10 of 10.
By being laissez faire and enjoying my adventure rather than focusing on the horn length and species they had me do several days of Impala culling, took me on their nightly beer and wingshooting sundowners, and I went and enjoyed the PH's true passion with him; fishing. I simply "went along for the ride" each of my trips, and the less I tried to direct or spell out considerations to the fine detail the better every trip went. I haven't had a bad PH yet though and this could bite me one day.
I'm an experience collector not a head collector, and this approach has brought more of what I hope for out of each African trip; life experiences. We walked up on black rhino in Zim, shot dozens of birds in warm nights with a rosy beer glow, and each day early pushed hard on buff until a remarkably sweet ending. I think I'll keep following the policy of asking any PH I trust immediately "What would you do, if you were me. I'm not here for a crate that follows me home, I'm after memories?"
They're usually taken aback a bit, and as mentioned the immediate response in Zim was fishing a beautiful spot, in the Kalahari it was a long Gemsbok stalk that we put more efffort into by far than Lion, and in Limpopo it was late evening Warthog hunting and long shooting for fun offhand with .375s and .458s at their airstrip. Seems like the question "What would you do?" with a smile busts through the client-hunter barrier and let's them know they can do no wrong with you. So far everyone has been great, and this approach may get a stinker yet.
