Ridges? who cares about ridges? Of course it's Klaa. STVI was written so to get everyone on board.
I actually put the question to Todd Bryant at a Brisbane, Australia, convention. At the time he didn't even know
that a few official books had connected his two Klingon appearances as both being Klaa, and he told the audience that the bumps were definitely different, so it was a different character. But I read an interview with him a few years later where he mentioned Klaa's demotion to translator, so it's more of a retcon.
