Goose25,
I shot Rowland Ward bushbuck and waterbuck off a Stoney-Point mono-pod and went as far as buying one to play with after that. Do I like them? Oddly enough, not very much. The shots that I took, I could have made offhand. African style shooting sticks are a lot steadier, if you can talk someone else into carrying them. I've got good useage out of Stone-point shooting sticks and homemade ones from sitting, and old fashioned position and sling shooting has worked out fine for me. Trees and improved rests seem to fill in the gaps.
If you need or want a walking stick anyway, give it a try.
