The only advice i have is to practice with what you will take along. Contact your PH and ask what sort of blinds you will use and then go and simulate the shots.
One common mistake is for first timers to Africa to suddenly go and buy a monster of a bow and try to pull 80lbs, "because African game is Tougher", this is a fallacy and leads to more woundings as a result of poor shot placement. Your 60lbs deer rig that you split arrows with is what you want to take along with you.
Beyond that your clothing and arrow selection are most important, you need to be comfortable in the blind, so take clothing which can be comfortbaly dressed up for cold mornings and stripped down for midday heat.
Arrow selection and most importantly the broadheads is one of the most debated things out there. My opinion is to go with simple solid performanance. In my opinion fancy fails, so stay away from mechanical heads, go with solid fixed broadheads with replaceable blades like the Muzzy or similar style, they simply don't fail.
One last consideration is that if you shoot a standard bow like a bowtech or mathews you will find parts easily, if not then bring basic spares along with you, cables, string, fancy cam attachments, etc. this is an investment as well as an adventure, don't let it go sour by cutting corners on your equipment. Ask your PH if there is a bow press too if you need one in the unlikely event of a repair needed. Also make sure it will fit your bow.
What equipment do you use now?
Good luck
