I'm going to say, since you have to ask the answer is no. But you will have to accept that here at Epic Ski that's not going to be a very popular answer.
Epic Ski is filled (at least of the people that post here the most) with racers, ex-racers, and skiing experts of all stripes. They will almost habitually recommend the longest ski a skier can use, on the idea that if it's even a possibility that once every few seasons you might
get the chance to ski 70 miles an hour down an empty trail it's worth lugging the ski around unnecessarily the rest of the time, will little or no concern as to whether or not the skier has the skill, or even the interest in racing down an empty slope.
My advise is going to be, use the shortest ski you can that does what you want to do. It sounds like you are not having a problem with your ski. So keep it... don't worry about if your ski length is "fashionable".
Here's why I am starting to think this...
I'm recovering from an injury, and have gone from a Rossi Bandit B2 @ 182 to a Salomon Lord @ 161, and I'm loving it. I have not yet found a down side to them. They are lighter, easier to ski, easier to maneuver, easier to transport... the list just goes on and on.
Now mind you, I ski in the South East U.S., so my primary concerns are speed control so I don't run down people on insanely crowded slopes, ability to make quick turns so I don't run down people on insanely crowded slopes, ability to make quick stops so I don't run down people on insanely crowded slopes, and ability to ski in man made snow, ability to ski in frozen man made snow, ability to ski in slushy man made snow, ability to ski in man made crud, etc. Your conditions may vary.
I think part of this is because years ago when I started on straight skis, when you turned you put most of your weight on the outside leg, and the inside leg's job was to keep you up is the outside ski cut out. so if you were on a pair of 210s, you really were only using 210 or so worth of edge in a turn.
With theses new skis you weight both legs more or less equal. So if you are on a pair of 161s, you are using 322 of edge in a turn... 112 more edge than if you had an old pair of 210s.
Just for reference, I'm 5'10" and around 270lbs, and pretty strong.
I have not had a problem with "over powering" my skis.
