I think the design of WTC1 is fine, what bothers me is the roof height. Back in the 70's, or even the 80's, 1300-1400 ft was pretty significant, but in light of the last 20 years, and China, Dubai, and Singapore, it's an also-ran. Spire or no spire, its still a 1300ft building. In that sense, those who destroyed the original towers did win. But that's just my opinion. If I had my drothers, this building would be scaled to the 2000 ft U.S. height limit, putting the roof at around 1540ft, and the observation deck at around 1440 ft -nothing extreme about that kind of a height bump- but its way to late for that now. I just hope someone is willing to break the 1400 ft roof barrier in NYC before the next ice age.
