Had the pleasure on riding the FS fgood few times and it is defenitely a freestyle kite. In terms of power and feel placing it between Best TS and GP is pretty spot on. You need to work a bit more on the timing compared to the TS but when you nail it the thing shoots straight up! Still you dont come down like a rock.
For me it is the most precisely controllable kite I have ever used. Even when over powered you can push the kite to the side and you don´t feel it is pulling you to strongly. Then couple of tighter turns with the kite and BANG the power is on!
Meybe not quite as easy as the TS and just by the feedback we are getting from the local riders most old TS riders are stoked about the thing and some might feel it is a bit of a handfull but they find their new best friend from the RS
Havent had enough wind yet to ride the RS (only got a 10m from the first shipment) so no personal take on it.
If you have the change go and test them out! You will be very impressed about how they fly and especially on how well they are built!
Ps. I am very much biased as I am one of the distributors but hand on my hear that is my honest opinion
