Interesting you say that. The engineers I talked to always told me that they preferred lower (sea level) launches because of disaster recovery (lower winds and lower potential contamination area) and because stats suggested lower launches gave more stability at the start of the flight when the rocket is typically most unstable. I am _not_ rocket engineer though. This is simply what I remember experts telling me >10 years ago. :)
