>>2907765I have this "kind" in the form of a Sirui PS monopod and its wide foot, yes.
>Let's say a slippery grassy hill tilting 30 degrees, would I be able to plant my monopos on such a hill and have the monopod stand completely vertical withour the feet slipping down the hill?Probably not, at least not with the one I have.
I mean, it could work just barely somehow, but it's definitely not a good idea. Use a tripod for that.
