All the responses were favorable. In summary:
- There is some sway, but tolerable with small yagis.
- Base rotor is better then top rotator.
- Rotating at base precludes roof/eve bracketing.
- US Towers is a good company with which to do business.
- Not as stiff as a lattice tower - understandably - interesting calc from
Rick, N6RK, for stiffness coefficient as function of diameter.
- Cable replacement if required for disassembly can get tricky.
- A couple of good links and photos were provided - Jim, KH7M
- Skip, KJ6Y, has installed many MA tubular towers as part of his business.
For an urban dweller like me looking for a tower with a small foot print and
low visibility, this seems to be a good choice.

So...what did you find out? I'm sure 1200 other TowerTalkians would be
interested in the comments.
