thanks for that. So as far as the frame goes, the only difference between the NFX and NFX "Sports" is the lower spreaders changeto P200's
(Of course the sail goes from Nylon to Icarex).
Not sure if the bridle etc are the same....
cheers and thanks
Edit: Other differences include in-built ballast (about 15g) and yoyo stoppers.
I think the bridle might be different. Also check that the 6mm in your kite looks like Structil because the cheaper kite might get generic carbon instead. Just a thought.
