Got a bug up my rear for a project, did some research, no joy. Are there smaller towers than 25G? Thinking something 6" per side, square, or triangle, ~20' height. Is such a design readily available?

That's 4% of the value. Could it be measurement error? I have suspected for quite some time that one of the items is off by 3%. The baseline of 003 rather than 000 when shorted is a clue, so that's t
