Which sonnet?

Liv wants her wedding reading to be from Shakespeare. Currently choosing among:

• Sonnet 18
• Sonnet 29
• a really beautiful passage from "Love's Labours Lost"

We're saving Sonnet 116 for the wedding officiant to read as part of the ceremony. Pretty much decided on Matt's reading (the only appropriate Decemberists song -- red right ankle.) Still need readings for N & J. Checked out Sonnets from the Portugese but don't think they'd be comfortable with any of those readings. More research...
