In 2008 Ricardo Campello tried a Triple Forward loop at Pozo Izquierdo. He landed on his back and was already pretty close to land it.
It needed about 7 years until Philip Köster made a similar good attempt during the 2015 PWA Gran Canaria Wind & Waves Festival in the final of the single elimination.
