Moon space elevator passing though Earth-moon L1

[neil]

100,000 kilometers though Earth/moon L1 is about the correct length. Longer rapidly decreases the mass of the counter weight needed, which can go to zero, I think. Longer also means closer to Earth which reduces travel time and slightly delta v for both directions. Isn't a distributed counterweight just as good as a big blob at the end?
Is yoyoing due to stretch transients in the tether? A modest amount of yoyoing may be like the crack of a whip allowing faster release speed from the end and better matching the the arrival speed of Earth to moon payloads, but timing would be difficult. It seems to me that the farther from the moon the payload is released, the sooner the pay load will reach any destination other than the moon.  Neil
