470 DR and a quick detach scoped 375. You can use the DR for close shots and following up. Have a bearer carry the 375 so you can switch if some PG gets in the way or if you need to take a longer shot. Then you can use the 375 if you tag out on the Buff.

Who are you going to Masailand with? I am going in November for a 10 day and am really looking forward to it.
