Hi Simmo... the SubframeSelector script lets you calculate and attach a weight (in a FITS keyword) to each sub based on the parameters for each sub (FWHM, Eccentricity, SNR, etc.) David Ault wrote a nice spreadsheet that simplifies the process, but it's still at a typical PI level of difficulty
The spreadsheet is here:

You weight the subs after they have been calibrated but before they are registered. After registration you can tell ImageIntegration to use the calculated weight instead of the default noise weighting. That means you can give priority to better FWHM and/or Eccentricity or any other parameter(s) you like.
Cheers,
Rick.
