Never hunted dalls myself, and only limited experience with Aoudad, but I too would tell you to check out the spartan bipod.
I wanted one for my hunt last month but opted to shoot off my pack. I'd gone (way) over budget on my rifle/scope so I had to let things settle down a bit before dropping that much coin on a bipod. I'll have one before Spring Bear season though!
I would not consider any other bipod on the market for hunting purposes for the exact reasons listed in the responses above. But, the spartan Javelin bipod eliminates about all of those negatives. It is genious. If you haven't seen it you need to check it out (
www.Javelin bipod.com). Its only SIX oz! Keep it in your pocket while hunting and it snaps on with one hand (magnets) when you are ready to set up. The only real downside is the price tag. 300 bones, and shooting off of packs/rocks is free.
