I'd get mesh from Riff on this forum. He probably has a pile of his "tails" kites stuffed in a corner. Nothing handles better in gusty, flying when you probably shouldn't be. I built my own for fairly cheap and fly it when I don't want to pull out my Djinn full vent. There a good first kite building project. If your flying solo in gusty high winds the kite doesn't need to be perfectly built.
A full vent Djinn would do the trick. As an experienced flier - standing in 30 mph winds = no fun! Yes the kite is designed to handle that, but being out in that much wind, especially a beach with all that sand blowing, not fun. YMMV
