Hi Mike, I didn't notice noise in particular and your images with the new cam have all been great, so the following is purely from a theoretical point of view:
Why would darks introduce noise (unless you didn't have enough dark frames)?
And I'm wondering about flats too, because regardless of the chip you'll always have at least a degree of
natural vignetting, due to the light rays striking the outer areas of the chip at an angle (pixel sensitivity depends on the angle of the incoming light). There will be dust doughnuts too, at least eventually.
Once you'ce created a dark/flat library there should be no extra effort required in applying this step to all your data. The calibration can be automatically applied in software like Maxim, so just thinking why wouldn't you always calibrate your data and squeeze the most from your camera?
So, not saying that your images need any of the above, but ideally I guess we'd all love to get the most from our equipment.
