Regards drizzle versus smaller pixels. My old ASI294 on my 80mm is just about bang on 2 arcsec per pixel, I recently used drizzle in APP on a set of subs I had and ran it a couple of times at different settings to work out where the noise started to become objectionable. First light with my ASI2600 (3.7 versus 4.63um pixels to make it 1.6 or so arcsec per pixel) was of the same target, unguided and with spacing still to be sorted, but to me the star profiles looked at least as smooth with 20 subs and all the tracking and spacing errors as the drizzled stack of 100 subs.
I suppose it says you can get a result both ways.
