I know this is an older thread but it looks like razorock version is back in stock, i was trying to get it for months but gave up and got epsilon blue, but for razorock fans it looks as if it was finally restocked this week.
I hear that the old Furbo smell's line Flood blue, but may be a bit stronger and longer lasting. IB has the newer version in. But the older version is to be available in a few weeks. Hope to give it a try. I kind of kick myself for not purchasing Floid blue. I guess I thought that it was such a popular aftershave that it would be around forever. So no big hurry to buy and try.
Interesting I do have floid blue edt splash and I bought Aftershave royal copenhagen and I think i smelled kind a like in the same direction. And I live in denmark so i think its a must have for danish wetshaver..
People in Italy speak very well of this one as closer to the original, it's the line Furbo Blue. https://www.trepiprofumerie.com/furbo.html
