@ Igoryak - Not my dept but Switch uses a fixed margin for all it's products which directly reflect cost of materials, labor, shipping, etc. and generally rise incrementally as time passes. Still a fantastic value and no middlemen taking a bite so you are actually paying for the kite only and not a dealer or distributor overhead.
@ Eree - Skepticism is good thing. Suggest you give it a bit more thought, preferably in 3D, and consider how and where the Spider allows the kite to change AOA. In a static state, the Spider has no tension. In the dynamic state, the junction is slightly ahead of the kite and the risers/front towpoint are free to rotate around the axis created by the wingtip corner and Spider junction. In a bridge bridle (what nearly all existing SLE kites have,) the axis of rotation is constantly changing smearing out the response and shifting loads along the leading edge as the angles of the intermediate lines change. The Spider basically de-couples the support mechanism from the AOA mechanism allowing it to tip freely with less bar pressure and quicker response. It also allows for a much shorter, tangle-free bridle.
Regarding flagging, this intuitively appears a problem and was an obvious concern. Repeated testing proved the kite falls cleanly out of the sky and lands face down in a stable position as the single towpoint is free to move well ahead of the kite.
@ Osprey1 - Thanks!
@ Eree again - If you prefer long bridles, Nitro4 should satisfy all your needs, especially being a heavyweight rider. We actually listen to our riders and a primary concern with them was shorter bridles and more stability. We found shorter bridge bridles lacking so embarked on a new path of R&D to retain the positives and improve on what they wanted. I think you would really find the Nitro5 a step forward.
