I went last year with a bw psa 52 at 28 and I generally draw 27 1/2 to 27 with 540 grain 35-55 gold tips. I did okay with a warthog, impala and kudu but never got a pass through on any of them. I'm going back in 2010 with a bob lee 50 lb. and 600 55-75 grain goldtips ( 300 upfront). You may not get the penetration of a 60 lb. bow with 700 grain arrows but if you are careful with shot placement and keep your shots under 20, you should do well. It was my impression and experience that the kudu was not as tough as many of the other animals. I was more amazed by the warthogs and impala. They will jump your string and laugh while they are doing it. They are also very tough once hit even with a decent shot. My impala ran over 400 yards with a good old double lung shot. No one told him that he was supposed to die faster. Last thing, enjoy yourself and enjoy the hunt. I was so concerned about penetration, doing this right, getting that animal and so on that I forgot to just breath and soak in Africa. You will have a blast. Bhill
