Pumpy full of wind, ram airs are so last year. Single skin foil kites are where it's at. Light, durable, safer to launch, and super drifty.
Single skins are really easy to dry out.
I launch from the side of window, fold the upwind tip over about 20cm, and find something small to sit on the tip, eg. a small lump of wood/stick, smooth rock, or your helmet.
