Same here, have done a bunch of ground engaging tasks and haven't ever had anything go wrong. Even sideways forces on the boom don't seem to matter. You shouldn't be worried about it bending. Thing is that the powerboom is practical, but from a physics standpoint is the worst setup you can have (because it is massively offset from the center).This means the powerboom is much more likely to have these kinds of problems. There used to be a video ( from JCB) where it was shown lifting and you could see a huge amount of slant in the boom. JCB later removed that video, probably because alot of people noticed the slant and they obviously didn't want that.
