We've all seen the Klingon battlecruisers from ST XI, and while they do closely resemble the D7 types from the prime reality TOS era, they are significantly different in a number of ways, e.g. slightly greater weapons capacity, hull details, etc. My question is, how well do these (more advanced?) vessels fit within the Klingon lineage? Are we supposed to believe that the Klingons also derived advanced tech from the Narada (which would contradict the Nero comic book mini)?
