Clearly the best statement is Tai Tzu Ying: "They only break when I smash them on the court. But that rarely happens." You simply have to love her.
Normally rackets are not designed for crash, but as an amateur who pay everything for myself, I will consider about the strength of my racket in double play especially when playing double with someone I am not quite familiar with. The only two rackets which were famous for its high survive rate in crash are Victor Supernano 6 and 7. They are famous for 'killing other rackets even without losing painting'. Majorly because of so called 'diamond frame' which is claimed to reduce air drag but actually not. It brings high frame strength by coincidence. On the contrary, I only use Bravesword series in single although they achieved great reputation in double as they are famous for surprising failure even in light crash (but could easily be restrung up to 30lbs as labeled).
