If you check the video here:

you can see that it has the clear/kevlar reinforced material in the tips and trailing edge. This looks like the same material that Naish used in the unsuccessful X12 in 2003. I had one and it was great when new but soon lost strength and I had to send it out twice to have repaired. Wouldn't hold the stiching very long.
Hopefully Windwing improved the sewing and glueing.
Either way... Props to Windwing for pushing the envelope.
So Scott... when are u ordering one??
