Interesting,,, it looks like it was done for Safework SA..
Pretty inconclusive, and not exactly what you would call exhaustive. The "standards " they used were not too dissimilar to Dave's, maybe apart from the addition of some fake seals? wt?.. I'm not sure whether they even collected as much video as Katana.
Easy read though,, and make sure you check the one page executive summary,,, and a line near the bottom...

maaaaate,,, Dave's got my vote.. I've seen his videos..
In the end, its a bit like someone once told me;
Its like seat belts and air bags.
Do the manufacturers give you a guarantee against death or injury?,,, and how many times you gonna crash your car?
I reckon the more that fasten up.. perhaps the more they'll stay away from surf breaks.,,, especially high risk ones during whale migration season..
and perhaps we won't have to shoot or net them along with the collateral damage no-one wants.
