I dunno what your finances are like (although it has never seemed to be toooo much of an issue with you over the years

) but If I had your gear (well I
almost have one of'em

) I would get:
THIS for the Honders and take deep high res wide field shots from Bigga with it, in relatively short exposures.
and use your ProLine 16803 with the 17" for galaxies from home (or Bigga if you decide to move it) seems pretty simple to me
No mumbo jumbo from me
