The cod/pollack rig looks like it might take some fluke. Who knows, maybe even a weakfish. But looks more like a take on some of our cod rigs.
Can you post a pic of the first diamond-haped rig you mentioned?
Europe, especially the Great Britan area, does have some odd (by our standards) looking rigs. When I was in London some years ago I picked up a bunch of lures at a shop that looked like they would do well for bass and blues. Some kind of spinning (rotating) lure they said was used for salmon. Looked great in the water, but even snappers wouldn't touch it.
ps- I remember the first time I tried to describe saltwater flyfishing to a Brit. She looked at me like I had 3 heads!!
