Can't help you much with No Mai Tsze. Emperor, as menioned is clearly on the slower end of the scale. My Sweethearts are much later plantings than my other trees. Kwai Mai Pink in my yard are all dwarfs but the tree they came from at Whitman's was not dwarf at all, so i think that is more or less similar to Kaimana. Bengal is vigorous, as is Mauritius. I would not classify Ohia as small, it seems to be somehere between Mauritius and Kaimana. Sorry for the poorly organized response. I'm a bit scatter brained this morning.
