What difference is there from Steve Renyard's Bungy Boom that's been around forever, does the same thing - yet it resets and wouldn't snag on things? There have been other designs and all have been banned for whatever reason. The twig looks to be a snagging point for weed, snags and the net.
I bet he's crying more now than when he thought it was going to be the one. But it's not!
I saw one of the Nash lads tying elastic to the bottom end of a zig line, so it's hardly a new idea, and the guys original design was exactly the same -a bit of elastic tied into the rig, supported by proper braid for when the elastic snaps.
To say it's a disappointment after hearing all the hype is an understatement!
