I used to find LR was the one ie 3x1.3, but with latest image scale on Jupiter, a 3x1.3 ME works best, sometimes only a 2x1.1 ME on a heavily waveletted image worked well.
Back in decembers AS&T, there was an excellent article regarding how much info can you squeeze out of a system??
Using ME and LR on things like imaging detail on ganymede and IO along with the encke division.

The author of that article has this on the web, worth a read
