This 21m2 tube is 6% lighter weight than a 21m2 foil
That right there is quite an achievement in itself
Not much to pump...3 struts + leading edge....2 1/2 minutes at most by hand pump to inflate
Deflating a big LW tube is quite faster than getting that huge amount of pillow air (1 psi).......
....trapped between the twinskins...and get it "all out" of those 2 small deflate velcro valves flaps
The reason for using a large foil for LW is becoming virtually unnecessary in this day an age
These are valid arguments
I've flown also and had all the big kites.
My first big one was in 2002 the Gutless F-One Mach1 18.1m
and the worst upwind machine was the 23m switchblade.
Seems like LEI caught up with foil types as far as weight,
but I'm still questioning the relaunch, upwind and wind range attributes,
which are very important for me
If the new 21m Zeeko has all the benefit of the 21m Speed3, than congratulations
