funny thing is that i noticed ... look at the spelling of each color ... how many letters does each color have ... that is the size of the kite (not always) but close enough
the green one is probably 5m ... 5 letters
blue & green is probably 4.5m ... will you let me know if that is correct ?
if the kite is thin (narrow) ... it's more for racing kite and speed kite (quick steering)
if the kite is fat ... it's traction kite (slower steering)
what about CobraKites.com ?
