"Open With" has duplicates

You could also use an "After copy" shell script to reset the launch services database. The command you use is:

/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

You can write a little shell script to do that, which'd look like:

#!/bin/sh
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

Save that somewhere, set its execute bit with chmod +x the-script-name, and then set it to run in Advanced options.
