I guess the 200 series is the successor of the acetate handle drivers. I personally would buy the 500 or 550 series. More difficult to clean though but feel better in my hands.

But you can´t go wrong with Knipex or NWS
ps: why the small 160/165mm size ?
Monte, would you say that Knipex and NWS are same in quality?
