I have hunted with guys that have guided myself as there first and only successful mountain goat Hunter who were just getting started in the guide business (I was a bit nervous about that at the start of the hunt but he turned out to be an awesome guy who got me on a 9 inch Billy on day 1 at 100yds for a kill.. .still talk to him often and consider him a good friend) all the way up to a guide / outfitter who does his own guiding and has no assistant guides. I treat all the same as far as tipping goes. If I get good service they get a good tip. So far I have never had a bad encounter on more than my share of hunts. That said my wife and I are taking our first safari in May with Limcroma. No idea who our PH is but if he performs well he will be tipped well. Doesn't matter if it's the owner or the newest PH they have. I like to leave feeling everyone is happy. You never know when you may hunt with them down the road.
