Yeah, I've seen discussions about these on another forum, along with some youtube clips of the production and testing. For those interested, do a search "Ginei lures" on youtube.
The level of detail, and the painstaking methods that go into each lure would indicate to me that their price must be astronomically high, and hence they are not the sort of thing I'd be wanting to actually fish with, especially for big critters like GTs
One for the collectors perhaps?
