This pattern I`we seen called "crowfoot". I made several, think they are wery nice looking and actually easyer to make than the ordinary setup. A bit more tricky to tune. I`we got another one ewen better looking but a bit more risky, think it is more for the look. I`ll try to remember to post it tomorrow.
I just looove bamboo, in all type of use and form. Got to love it when I made kites. There are some real nice bamboo bikes on the net, some with thicker "tubing".
