Speaking as a Treebler, I have watched 'Taters chop trunks on many threads here. The expectation is that the tree will grow the branches it needs in some years and be styled into something with a proportionally large trunk & nebari because you chopped it. It rarely works that way. It is soon evident that the twigs that pass for branches will take a long, long time to grow to any shadow of a decent branch in proportion to the rest of the tree and that is achieved by thickening the twigs by growing long and chopping a few cycles. All of that takes years, and sounds nice, but the nature of our business is surviving winter and drought and winds and disease and pests and bad luck, and is commonly interrupted by the death of a strategic branch here or there requiring a shift in strategy to produce a replacement. It's you against the years in the end, and the years have a better batting average. I have seen here many, many started and damned few finished. Go figure.
