I agree with Sweet T via
@Godfather, find what your specific rifle likes best and stick with that. The TTSX and A-Frames would be where I started. I'll also recommend the Federal Premium Swift Scirocco II 180s. I've had great success with this round this fall/winter on whitetail and hogs.
Congrats on talking your wife into an African safari for your anniversary. If you're looking for something the wife might enjoy midday between your morning and afternoon hunts, have your PH take you guys into Bedford for coffee and dessert at The Duke of Bedford hotel. The hotel is actually really nice and has a great courtyard that's connected to a bakery called Apprentice Deli. De Oude Fabreek in Bedford is a nice spot for a meal - nothing fancy, but cool setting and good food.
