Thanks for the feedback, Alec!

I was wondering if the bolt on c-tower was over kill.  Also, I've been
considering the dome c-tower/hatch.  Less work sounds good to me as well,
which is kind of the aim of this design.  You are giving me the impression
that there is more distortion with dome than the four viewports, some how
I would have thought it the other way around.

Cheers!
  Ian.
