All the leading edges are the same, so you are only comparing the venting portion of flight dynamics.
It will "bend less" in the middle as the wind speed increases if you use the most/more vented sail
the wind speed doesn't matter, they're all framed the same, only the feel in you hand matters,.. do you want it surging and twitchy (fun-flailing, alone for example?) or silky smooth and graceful (add vents until satisfied). You can enjoy an over-powered kite more easily, flying on the edges and low and slow across the power zone
your next frame is the Skyshark CXL 150, stiffer fatter and it fits into each sail,... when do you like that mass, low wind flailing or upper edge gusting.
Experiment and keep notes if you need to,.... you are developing your own sense of feel and perfection. You have a great set-up to compare upon as well, ENJOY
