Practice shooting through small openings, 4-6 inches wide by 12 to 18 inches tall. Sitting in a dark blind looking out a little opening can mess with your depth perception. Also remember that you will be shooting uphill from a pit blind at anything bigger than an Impala and less than 20 yards away, this is different from what most people are used to and you have to adjust your point of aim. Try to shoot directly above the front leg on broadside shots, if you shoot behind the shoulder crease like is normal for here you will be in the guts. Your setup will be more than adequate, you made a good choice in broadheads. I believe wider is better in Africa and if your arrow makes it to the far side ribs that is all you need. Quiet your bow down as much as you can. Take a journal and put in entries daily, it helps pass time in the blind and it is really helpful after you return home to jog your memory. Take a lot of picutres and a video camera in the blind is very nice to. You can reavue your shots in slow motion and verify arrow placement and it is nice to have your own hunting video. That about it right off the top of my head but feel free to contact me if you have anymore questions. Joseph
