Huchen fishing Slovenia

[Dorthbison]

Hello all,
Planning a trip for Huchen fishing Slovenia and could use some pointers. I've heard Slovenia is a top spot for Huchen, but I've seen mixed reviews about the actual experience. Some say it's incredible, while others mention issues like crowded spots and unhelpful guides. Is it really worth the trip? Also, is it better to hire a guide or go it alone?
Any recommendations on specific rivers or areas that are less crowded and more fruitful? Any advice or experiences would be really helpful as I plan my trip.
Thanks a lot!
