Training ??? Are we both talking same commercial ops bush flying? It is not home at mom, you have to figure out yourself. Just kidding! - kind of.
When I was in Maun, it was pretty easy. When you were just looking to collect commercial hours in 182 or 206, it didn't matter. The selection process, and because everybody was talking to each other, was such that you had to pick what was offered to you. If you planned to go turbine, the only choice was Wilderness, but that also meant to probably spend some time at some of the others, because everybody wanted to go there. I lost contact to the Botswana fellows, so in case you have to see whether somebody else operates Caravans there today.
