Ouch! Were the last two paragraphs in reference to the Fort Wayne station or WDTW?
It reads like they had already decided who would get the license and the "auction" was just a formality, a cover story. Perhaps you should have a company with a deceptive name (one that would have the seller believing you won't use the station in a competitive way) to bid for you next time.
WDTW's array had four types of towers (!), all of the same height. The Northeastern tower was thick (I suspect it was built for use as a daytimer on 1540, pre-CBE), the SE tower not so thick, both central towers a little thinner yet (I suspect this was for the move to 1310 with Class III operation at 1kW DA-N), and, finally, both western towers quite slender indeed (likely installed for the upgrade to 5 kW DA-2).
One more note - I've been looking for whatever defines a "tubular tower", and if that literally means a tall standing one-piece tube, WDTW did not have any, they were all lattice (IIRC, the eastern two had "X" braces and the other four had straight braces).
If the steel forming the lattice was, itself, steel tubes, rather that rods of soild steel, I would not know.
