I have climbed Liberty Crack 8 times over the last 15 years and could give you lots of beta. But you know, the first time I climbed it was the best (before I learned the many "tricks" that enabled last year's "speedy" ascent). With the on-sight ascent we took a long time, and despite fixed pitches, darkness covered the rock before we we're able to finished the last ropelength. This timing mandated rapels across moonlite quartz crystals, and a long, tortuous, thirsty decent to a 4AM "party" with "cold ones" at the Van.
It would be my pleasure to give you all the beta you might need (including gear selection, belay stations considerations, best summer weather patterns, and safe lunar cycles), but I think you'll have more fun if you just go to the base, uncoil the rope and go for it.
