In that price-range I'd lean toward the new production Model 70, since it has just about everything I want in a big-game rifle. My .458 in that model shoots like a varmint rifle, which though is a more or less useless on a heavy is still gratifying. I particularily like the safety, not so much for the 3 positions but for the way it locks the striker. On a safari you will probably be cocked and locked for days at a time while surrounded by people who give the impression that they are trying to get shot. Every bit of piece of mind helps.
I hear you on the safety, I too like Winchester, and Ruger, for that- physically locking the striker. Sometimes I questioned my PH and tracker's will to live.
