Has anyone ever considered using a bipod instead of a tripod (or monopod)?

I use a monopod most of the time but there are times when I really would have liked to (and should) have used a tripod however the hassle of setting up my heavy old tripod has discouraged me from this.

On the weekend I saw, for the first time, a bipod in use. It was a Primos Trigger Stick and the lady using it was moving along the bank of a dam and was able to very quickly adapt to changes in the fairly rough terrain and continue shooting. The way she used it gave her much more stability than a monopod and whilst obviously not as stable as a tripod, it gave her much more flexibility.

It struck me as a reasonable compromise and a quick search shows them to be fairly reasonably priced.

Cheers
