@hinmo24t - I watched that video, most were Norway maples, but at least 3 were Acer palmatum and 2 were trident maples. One I think was Acer ginnala, the Amur maple. You could tell because they looked in proportion where the Norways all had leaves that were too big. But the majority were Norway maples. Good illustration of the issues with Norway maples, but also a few Norways did look "pretty good".
