As requested, a couple of pics of that hybrid hone I got from eBay.

... and with my tester/guinea pig straight, the "£1 superb".

First reports... it's not a natural combo as I was hoping it was. There's a definite man-made split/join, with what seems to be a small notch filled with silicon. It's a bit disappointing, but seeing that it's larger than the coticule I've been using so far, I can overlook that. Onwards with my search for a BBW/coticule combo.
HAD..? Wassat?
To the sides. So far, all I can really report on is the slurry production, as I'm not experienced enough to say "this/that/the other natural hone produces x/y/z results". Here goes. The marbled side (hybrid? coticule? Les Latneuses?) doesn't produce much in the way of slurry. It's quite watery and is slightly milky. The dark side (BBW?) doesn't hang around with its slurry production! It's thick and plentiful!
Other than that, that's really all I can say about the stone. Apart from its marbling which looks gorgeous in both wet and dry states.
I'm a bit confused about where the hone sides would go in progression. My progression so far is Shapton 1.5K bevel setting, slurried coticule, stay until that's just water, then finish with the Thuringian. I'm guessing from the Shapton 1.5K bevel setting I'd go to the dark/BBW side first. Work with that side until I'm just using water, then on to the marbled side and again work until I'm just using water? Then after that, I'd go on to the Thuringian..?
As always, I'm grateful for any help offered in regards to this new addition to my stone collection.
