All the hype around the Aluula OR kites must have caused many sleepless nights at Duotone. They had surely planned the Penta TX as the next big thing in kite tech and then that space shuttle landed before they even launched their E-Truck. Don't get me wrong, all my due respect to the team at Duotone and to the supplier who developed Penta TX. I do believe that it's the right approach to material innovation and evolution.
And Aluula is in my opinion just a super high tech stuff in testing phase before it hits other much higher potential applications than kites.
Not scalable production (to bring cost) down, same as cuben fiber btw. A nightmare to assemble. And needs time to prove longevity for this application. A Ferrari basically.
As for that lame video showing nothing more than what Duotone published already in their last magazine (p. 80 / ULW project), I believe is just a dirty marketing trick (therefore not their own production) to draw the attention away from Aluula until they sell the planned SLS kites and come up with this technology or similar.
It would perfectly match their market leader strategy to have all their kites' LE made of Penta TX and an exclusive Aluula edition to whip the cream. Duotone can pull this off better than any other brand at the moment.
Sorry for the long reply
