Cite only by DOI in rebuttal
Make it easy for your reviewers to get what you are saying. Just a DOI is really hard for a reviewer because they have to walk to the computer, look up the DOI, and all that. 

If you don't want to provide the full reference, just say "see Schneider et al., cited in the paper". That way, there is an easy place to go to to find the full title and reference.
