OK, now that we are clear on your skill level, I think the GO 175/171 is probably your best choice.
It may be a little more difficult to uphaul than the 200 liter you've been on (a bit less "float" and perhaps a little more "tippy" due to not being as wide) but you will get beyond that fairly quickly.
It will also allow you to progress and may continue to be your "light wind planer" board for many years to
come. Good choice!
