It depends of the type of tree. Ash used to be used both for firewood and timber in France. I have ~35 250 year old ash trees like this, a good chunk of the branches are straight, just not as vertical as the ones from the technique above (which looks really neat). Those have not being well cared for by the previous owners though, I'm quite sure that with better care and selection of buds they would have produced more straight branches.
