It shouldn't make any difference.

Again, I suspect that the difference will be so small as to be negligible.
Pick one in the middle of what you're likely to edit at.

Perhaps run a dispread with a simple chart and save spectral data so you can
look at differences afterwards? It's unlikely you'll need to extra observers
for anything other than experimenting though. A corresponding chart done
with your Spyder within the next few days should still be usable provided
you keep settings the same etc... This should reduce the amount of time you
need with the CM.
