You raise a tough question, [@SleepingSilence]. I believe the most important thing here is that the level of tech makes sense for the character's status and occupation, and we need to also note that a cyborg is, in the end, the sum of their parts. A man with a reflex booster, flash resistant eyes and a smartgun link will be a much greater threat than, say, a guy with the same reflex booster, a biomonitor and skinweave. Things tend to work together. The example for zooming cyberoptics in Cyberpunk 2020 is, I believe, 20x magnification.
