I have an API Grand Slam Shooting Star. It has a removable front bar which stays off of it. Im 6'4 325. The only problem I have is that my hips are wide enought to where they rub on the padding a bit when I stand. The stand isnt rated for that, but it holds nicely. As long as it is set level it is as stable as can be. Im not advocating using a stand rated for less than your weight, just saying that it works for me.
