Ive done the same thing on hang cleans,with a 3"bar.When you clean them,it feels hard-imposible to keep strait arms and just use your hips and traps to pull it up,because it feels(to me)like the bar is going to be ripped from your hands,from your body accelerating upwards so fast.It would probably be best to work on doing them like you would clean a normal bar,and working upwards in weight.I would guess that you would progress really fast
