Any input on fly fishing in Slovenia?

[Keunkotk]

Hey, I’m trying to book a big fly fishing trip (thank you tax return) and I’ve got my eye on SLOVENIA! Has anyone fished there? I’m looking primarily in the Tolmin region - the rivers look incredible and I saw a “Marble Trout” somewhere online that looks like an amazing species. I came across flyfishing guide service Slovenia, which is where I’ve seen most of my information… does anyone have any tips or suggestions for this area?

Might be tough getting some feedback on this subject.  That has to be an extremely rare fishing destination.  Sounds like a fun trip but I know a lot of angler and don't know anyone who has fished there.
