Pick A Tower - Help!

I'm stuck and I need your help!

This is of those projects where the program name changes a dozen times and you're finally left with two days to design a logo with what (you hope) is the final info.

I can't decide which is the most effective… probably due to the fact that I've been staring at this for the last 24 hours. I'm leaning towards the one on the top left, but I'd like some Dribbble community input.

Imagery is based off our iconic Star Building tower. The "T" is readable to me, but I wonder if other people might miss it.
