From what I have seen so far the speed difference between the FX-One and Blade is not that spectacular. Although I have not yet seen a 1-up Blade so that might be different (The 1-up rating of 100 should say its a lot faster though).
On elapsed time upwind the Blade is a little bit faster and downwind the FX-One.
I think the Brits had a mixed event without rating and showed that they're pretty equal.

How are your experiences with the jib? (Selftacker?)
