Some quality climbs offered above!
The NW Face (aka Boving route?) on SEWS rocks, and only has a brief stretch of french-free-able .11a, which might even be .10+ if measured against the first pitch. The first pitch is a somewhat heady .10+, though. The pitch with the Boving roofs is fantastic.
Also, for a longer route at approx 5.10+, consider Freedom Rider on Lib Bell. The Medusa Roof is a pretty outstanding feature.
For the traverse, recommend starting low and direct-ish with the Barber Pole route on Lib Bell, fwiw.
