I've got a few mates that fly/have flown ATRs all over african on contract. I have to say most of these guy but not all went in with about c1500 hrs TT and c500 hrs twin. The one thing the ALL did was put in the leg work. Maybe it's because Africa is a bit old fashend but you've got no chance unless you see them face to face. I don't think any of them went in with TRs but I can't be sure of that.
Go for it
