You dont want the slamman, when i used it, it felt really "unstable" to me.

What you need is a freestanding man, you can put as much water/sand in the barrel as you want so it wont tumble eassilly, and the actual body mold dont break easy ( i've had mine for about 6-7 months and there only damage is a split under the nose )

but then again, you will need to buy another coil because my one pretty much screwed up through all my hooks and the screws just fall out now. But i think its way better then the slam man, its more of a sparring partner if your friend dont want to get beat up on.
