we ran this yesterday at alightly above medium flow.

imho this is better rated at class 4-5 (6,6,5)
i'd compare the overall difficulty to Wellerbrücke race course on the Oetz river.

(no trees btw.)
the two class 6/"unrunnable" rapids are right at the put in, beneath the roman bridge. the class 5 is shortly after that. it is best portaged on the right (scouting it is better on the left side though)

excluding the class 6 rapids at the beginning the whole run is only three proper rapids. if you dont feel comfortable running the class 5, not really worth your time imho.
