I have a Fons and Porter marking pen. it actually functions just like a mechanical pencil, but the "pencil lead" pieces are white and mark on dark fabric really well. water will take the marks away.
I have never used a pounce pad, but from what I understand, you would just use it to mark a small area at a time. otherwise, yes, the markings would rub away when the quilt bunches up or whatever.
also, if you are need marking for free motion, such as to make the feather spine or a general line to follow, I have also been known to "quilt" the line but use no thread in the needle/bobbin. this leaves a line of holes for you to use as your guide.
