I have the alloy hinges on mine.
I understand the sentiment about rather having a weak point, but as everyone who has a similar style awning, they have learnt to always peg it.
If pegged down nothing should break. I always have mine pegged down now, and funnily enough was after a similar incident where I learnt my lesson. Personally go for the alloy hinges, much stronger and more durable IMO.
