I'm not trying to suggest that my preference is shared by all Klingons or all Klingonists. It's entirely possible that if Maltz heard about this discussion he'd think I'm a pedantic weirdo. (ghaytan mujbe' net jal.)

"Romulan hunter-killer probe" might have been a bad example to argue about, really, since it already exists in canon as a set phrase. (I just think the set phrase could be better!) But if I were writing something about Ferengi jokes, I'd use quvHa'moHbogh 'ej QeHmoHbogh verengan qID instead of the alternative unless I had some compelling reason not to.

Features getting retconned out of errors because Okrand slipped into "English brain" during a translation is not quite the sort of thing I was thinking of. My feelings are more like this: Because the original English lines are often written by people who don't know what features Klingon has, the translations don't always take full advantage of those features, or they have some awkward phrasing in order to match the English. Okrand usually seems to stay as close to the original phrase as possible, and doesn't seem inclined to add meanings beyond what's originally written in the English. So, for instance, would more canonical Klingon lines from TV and movies use -bej or -ba' if the episode writers had known that the concepts of "certainly" and "obviously" were just single-syllable suffixes in Klingon and wrote the English accordingly?

One example I think of a lot is this bit from the paq'batlh: nItebHa' molor HI''a' SuvvIpghach puj je HarghmeH yeq chaH United to do battle together! Against the tyrant Molor! Against fear and against weakness! SuvvIpghach works fine in this context to mean "fear". But would the English line have contained the noun "fear" at all if the writer knew that Klingons usually talk about fear using verbs (either with ghIj "scare" or the suffix -vIp)?

In other words, when Okrand is translating someone else's English work (TV and movie lines, the Warrior's Anthem, the paq'batlh, Shakespeare, etc.), the English phrasing style sometimes shows through. How would Klingon "look" if it was more often written starting from the Klingon? What words would get used more often, which suffixes would be more common, what sentence structures would we see more frequently? That sort of thing.
