I been, I seen twice and I sat front row.
He had Scotty there for demo, and he showed video of the log levitating technique using the blue and red ropes off other trees with dynamometers for tensioning and lift the log off the cut and moving it away. Very impressive mathematics, which I believe he also takes a lap top and crunches the numbers.
Where, GreenX Sydney maybe 2003 region.
He also displayed the wire core flip line that near cost him his life as the wire broke but he decided to use 2 flip lines. I mentioned to him (he may have forgotten) that it's a design flaw and all those wire core flip lines should be recalled and binned. I also believe he lost a friend or fellow worker to a big regnans, the guy fell. I'm not sure if that's flip line related or not.
I get my flip lines made, I use New England blue highV. They pull the blue core out and shove in 1/4" dia stainless wire. They then place the lot around a thimble and crimp it plus stitch it. Far safer.
I have shown this to many arb people and shops but to this day no-one gives a chit and the flip line where the wire core does all the flexing is still on sale by large "reputable" manufacturers.
If there was ever a person to change this procedure it would be Graeme with that flip line he has as evidence. The reason why this happens is because like getting a piece of wire and for ever bending it back and forth it eventually breaks ... same with his because he's climbing those large trees he advances his flip line with the wave technique, this puts a lot of stress on that wire core (and it's stiff wire) right where the thimble is, and it's only the wire that is there no rope.
I have put a pic of mine so you understand, mine is wire cored but not so stiff.
