All good advise. Have the tree looked at by a pro. If very large have one of them take it down. When having it cut into planks cut for the best yield of figure. You are better off with a few great figured blanks. that are cut correctly, than a hundred blanks cut poorly. One perfect exhibition blank is worth more than ten almost exhibition blanks. As to if the tree has figure you never know until you get into cutting it up. It is like a box of chocolates, you never know what you get until you bite into one.
