Weight tubes can be purchased and inserted into your arrow shafts to add weight. As far as changing up your set up, I thought the same thing when I went. I wasn't too keen on the idea. But after seeing that my equipment did to a blue wildebeest at 37 Yds, I never changed back when I got home! I have never been concerned with speed. I want quiet. Shot placement is the key. African game kill zones are much lower and forward than NA game. Easy way to find the aiming point is draw a horizontal line thru the middle of your animal. The drop down and draw a line again. Now, come straight up the front leg. Where the front leg and the first horizontal line meet is your aiming point.
Good luck and keep us posted. Where and when are you going? Who are you hunting with?
