Pat,
I've been using the Stoney Point Bipod and Tripod
http://www.stoneypoint.com/convertapod_index.html sticks for about 2 years now.
I first started out with the Bipod and after about 6 months bot the additional "stuff" to get it to a tripod system. Now, I must use a walking stick just to get around and this stick is strong enough to hold me up (215lbs) in all kinds of situations, up hills, down hills, thru the mud, small creeks ect. I find it to be a quality product and worth the price.
I fold it up to walk with and then use the tripod for holdin my shotgun in turkey season. If it's deer season, I just use the monopod. When I hunt varmits, I usually set up with the tripod.
Dave.
