And at that RASA focal length, 620mm, smaller pixels have a lot to offer in terms of resolution,imho.

With a fast scope and heavy light pollution sky limited subs will be short on a CCD camera too and there will be negligible difference in the outcome.
Smaller pixels may be more suitable depending on the resolution/FOV trade off that David is looking for, but they will also collect signal more slowly.
