Full content view mode per role
Oh, It looks like I've found an answer myself, so I will post it here in case someone will have similar issue. One of the solutions (I am still not sure if this is the optimal one, but it works) is to use module Contextual View Modes (It requires Context module and Entity API). With this combination of modules it is possible to create context rules where in Conditions section there is particular user role and in Reactions one must define particular View mode for Content Type. And that's it! It just requires at least 3 modules to be installed, so maybe there is some simplier solution...
