I don't remember the second pitch of No Glow being anything but a pleasant 5.7ish climb up and around a corner and up to the roof.
Williams has the No Glow traverse as 5.5 R. It's spooky, above an overhang, harder for tall people, and makes me nervous; a fall would result in a fairly long pendulum. Easy climbing after that up to the crux, if I recall correctly.
