[inferno]

for a waroo, i can really only think of two main ways,
one is to anchor off the CL to a fixed object
two is to set up the kite, hook in and walk perpendicular to the wind till the kite spins around and rolls over and launches

but you definately want to practice these in sub 20 untill you get used to it, also with method two, use the scott technique of one hand on the QR and the leash on the outside line until you get the kite in the air and are sure its safe....
