The other thing you might want to consider in bipod choice is snagging, especially if you're running around in the brush with the rifle (e.g. game hunting, zombie killing, competition shooting, exiting vehichles while armed...). I decided on one that is slimmer/smoother and has less protuberances, odd angles and had legs that could fold either way so it's less likely to snag on belts, straps, clothes, brush and branches, dead bodies etc.... One less thing to worry about when SHTF IMO.
