What zoom level are you having trouble seeing them? At Zoom 21 and higher they only show as outlines and can be hard to see. At lower Zoom levels 21 and less, they show as solid dots, then at Zoom 20 we add the Wind Barbs to them. We've not heard much pushback on this change.
A big benefit to the new dots is when there is nexrad on the screen the colors are clear and defined, whereas the old Metar shading became blended and muddied up with the Nexrad Radar. The larger transparent metar circles were many times confused for TFRs, Stadium TFRs, etc.
I'm not saying its not an option, but it definitely cleans the screen up and reduces such confusion. Additionally, the newer Wind Barbs are more clear and standardizes too. We may just need to tweak the size, color, representation at zoom levels. I'll raise a flag on this for consideration. Thanks for your honest feedback.
