Rain shadow often the other side of the Gottard Tunnel, but the routes are mainly slabby granite, all grades. Vaguely remember going to some Italian classic limestone near there somewhere.
Lehn near Interlaken has some pretty steep stuff. Dunno about perma-dry but I climbed there when Wenden was wet and it's very good, though the best routes are probably in the 8s.
Lammi near Meiringen, Lungern also near Meiringen. Paschga in Eastern Switzerland near Sargans, Bürs just across the Austrian border near Feldkirch. All have a good choice in the 7s.
