TBH I don't really notice the size of the trees until I see a car driving down the road that has trees beside it. Either the car looks tiny, or the trees are huge.
I wouldn't mind seeing what small trees look like, or have the ability to scale the tree size without reducing total area covered (smaller size = more trees placed to replace lost coverage) as a option. But in the end, it doesn't really matter as the last thing I'm doing at 500kts and 15000ft in my M2000 is wondering if a tree is too big..
I live on Vancouver Island, Canada, where some of our Red Cedars are about 250 feet...
