Mine was in 09 at Burger World in the Mentawis.
All the other crew were sitting way out the back and it was a bit manic so I paddled to the inside where a nice right was barrelling to almost dry reef.
I had been sitting there for about 10 mins waiting when our guide paddled over to see what I was doing, I was miles from anyone.
Just as he got to me a real nice wedge came towards me, looked to be over head. I paddled into it and took off, and back doored the tube. It would have to be the cleanest barrel I have ever been in and I was a bit mesmorized and was lucky to get out as it pinched at the end, luck not skill

Our guide paddled back to the pack to tell them what I was doing and a couple came over not before I had a couple more, but the first one was the biggest and best.
I was glad that he saw it
