That has nothing to do with me telling you you were being hard headed. The fact remains that Kishi drew him a Susanoo and that Kishi was editorial Supervisor and concept creator for the Shisui story, DB4 confirms you only need both Mangekyo and to be able to use both eyes techs to awaken Susanoo, which was also shown in the manga and stated by Sasuke in the Kage Summit. You can then use it without eyes or when completely blind, or in normal Sharingan state.
