So far have used the F-Series (Freeride) and P-Series (Performance) with most time on the P.
The F to me seems to feel most similar to something like a Fuse when in 4 line mode . Still yet to try it in 5 line mode but switching to 5 line (This also removes the bridle and pulleys) supposedly makes it more aggressive, direct and dynamic. This could be good for somebody to learn on in 4 line and when they progress switch to 5 line.
Been riding the P-Series extensively lately with some great sessions on the 9m. Feel is somewhere between a Torch and Vegas.
New kite being released shortly is the S-Series as a dedicated wave kite. I have it on good authority that this one doesn't drop from the sky and isn't made from cheaper Korean cloth, awesome
