That Diablo is toast, better send it to me.
Seriously though, the Diablo v1 is an amazing kite! I love my 11m. I even put it in a tree, ripped it in half, sewed it back together, and it still flies great! If you have the ambition to foil in low wind, and to understand and tune foil kites, then get it repaired ASAP and keep flying it.
Yes, it flies totally different than an LEI. It’s just a different skill set that once you learn, it’s easy. If your future foiling goals involve going fast then make a bar with 15m lines and use that for a while, then shorten to 11m lines and get used to that. With a decent trim system, and foiling skills, you can use it into the low 20s mph. With longer lines, you can be comfortable in single digits.
That said, if you’re a wave-riding nut then maybe ditch it and that Taaora race foil and get a wave setup and kite.
