I have tried all the above and still have a couple that have survived. Just bought the bog pod tri and swore I would NOT spend the money on tripod, especially the bog pod. Well, now I am eating crow, I won't need another. I can use it sitting, kneeling, and standing. Works on uneven ground great, swivels, and can adjusts to the height u need by extending the legs or just spreading them wider. I can keep my rifle on it while my shotgun is on my lap and not worry about the rifle tipping forward or back when wheeling the shot gun.
Spend the money once or spend the money 4 to 5 times until you end up figuring it out. I thought the bog pod was just another marketing gig that was way over priced, but after pricing up the versa pods, the stoney points, and the heavy and clunky harris bipods I have bought, I am kicking myself for not buying one sooner.
The harris bipods are great for shooting varmints when not on the move, but don't care for them when having to be more mobile.
Johnny Stewart's sticks are the best bang for the buck, you can't go wrong with them if you don't have the coin.
