(High Strung fun!)
The Synergy 333 is a cross beween a dual line and a quad line kite. The same spatial thinking is required as for a 4 liner but with a definate twist. This is the only kite I really have to "think" thru as I fly it. A 10Kph min steady wind is what you need to fly it successfully. Turn it around and you can take a 30+ kph wind with no problems. I call it the mind bender!!
