no wind is like indoors, you MUST use your feet,... think the "up & over" technique
Plus, you must use the field walking around as well as that crazy slack lining.
How much room dictates how long of a line set to apply, then just match a kite to pull those strings around,
I use 15', 30', 50, 60'(50#, 100#) 100's (50# and 100#), 120's (50, 100, 170#)
Fly indoor, SUL, UL, standard, mid-vent, full vent, ultra vent, mega-vent and thong-butt bikini vented
