Re: bi-pod poll
My bi-pod is a Harris, but the Atlas is a much more versatile item though there are Harris' which have similar capability, just not at the level of performance (nor price).
I voted sometimes because there have been instances when the bi-pod worked just right for me, but at other times I've just shot off my pack (or whatever).
In any event, I'm planning on making a rifle rest adapter for my CF photography tripod so I probably won't need my bi-pod much longer.
