I believe you are correct here Rick; whilst upsizing and stacking can result in smoother data and some marginal improvement in resolution, the drizzling process is not the same and can produce much larger gains in resolution for undersampled images. There is a lot of information on the web about drizzling - here is a good site that explains the concept quite well with a worked example:

Bert, what is the image scale of your system (arcsecs / pixel)?
