Could be yes, I also visit the EC forum. and I'm dutch.
Slopes 7 and 9, did the red one every day, and the black one a few times too.
We stayed in a B&B in "See" which is a small hamlet just above Soelden, in between the valley descends to Giggi and Gaislach.
In the afternoon, when taking the 7, and then going left at "'s Pfandl" restaurant, I could descend all the way to the B&B (50 metres walking).
I liked slope 10 better; but that's personal taste.
IMO the best slope in all Soelden is slope 1, especially the part from where slope 4 joins. Wide, perfect constant pitch, good firm snow, quiet.
