I've used sand base bags and dummies (with sand bases) and like grawl said, they tend to fall over. Also with the dummies its easy to tear a hole in the neck or face then the head tends to go all soft and floppy.

In my experience the best bag ive used is a long bag, with the bottom resting on the floor. reason for this is 'cos with long bags u can do low kicks and its also great for punchin. With the bag resting on the floor it will represent a person standing. Also it will prevent the bag from swinging. In my gym all our bags are hanging on bungie ropes so if they swing they also bounce, and hit the floor, this also prevents the bag from swinging too much. (not a long piece of rope just, about a foot or so, but ull need a long piece of bungie rope so u can wrap it in the chain on the bag and then onto the rack a couple of times)
