Ha, that's neat!
The fuss is people don't get it by just looking at the dormant 'cat's heads' with no leaves, think it looks nasty.
I think they look like lollipops when they flush out, insted of the nice scaffold of a regularly pruned tree.
But, when its done from the get go because of limitations due to power lines or other obstructions, at least its functional, beats the hell out of topping!
