Forgot to ask, how does it compare to the SB given your descriptions in your first post?
I haven't flown a 2012 or 2013 Switchblade so I can't make a direct comparison. My buddy has a 2012 Switchblade and tried my Lithium 12 briefly. He liked the turning, power and smooth control. Definitely on par.
I have heard that boost and hangtime is better on the Lithium but am yet to confirm this.
Also, the lines come with sections so their length can be adjusted by removing sections.
I will try the light wind configuration too - according to Airush tying an extra knot below the standard setting on the rear pigtail will help when unhooking and reduce back stall when kiting in light winds.
