Some of the sentiment being expressed here is a little concerning. With takeoff power set and you find yourself barely bobbing at 2 foot on a bubble of air you are too heavy. Simple as that. Nothing more to think about. Lower the collective to flat pitch, kick somebody out, and try again. This talk of running take-offs is utter bollocks. Save your running take-offs for when you have 1000+ feet of flat level asphalt or concrete in front of you, on your annual check-ride. This is not something to be tried in the circumstances we see here.
