Slovenia fly fishing

[Thastings]

Hi, Looking for recommendations on Flyfishing guide service Slovenia, but feeling a bit overwhelmed by the options out there. Not sure whether to go with a larger, more established company or a smaller, local outfit. Worried about getting stuck with a guide who doesn't speak English well or who doesn't really know the area.
Anyone have any advice on finding the right guide service? Also curious about pricing and what's included in the packages.
Any input would be greatly appreciated.
