The roof crux move (I can see how if you're shorter it's tough to reach a hold). There's a bolt right at the roof so it's well protected.

The route
The 10b boulder move. The variation to the left keeps the route at 5.9ish

The slabby crux. Even at 5'10", I struggled to clip the first bolt (and then after trying to get past the first bolt I fell so I wouldn't recommend just going for it if you can't clip it first).
This photo was taken from the base of "Flake Fest" just to the left of Sonic Boom. You can see the wear pattern along the flake/crack in this photo where Sonic Boom climbs. The start of the route is located within a shady area (beneath and in the trees that you can see in this photo. Just look for the first two bolts about 10-15 feet from the ground.
