Saying any ski will break in park use, durability is a hoax is such a brain fart. Yes, it is partially true but it's also mostly bullshit. It's like saying you can't choose the way you die so there's no point trying to live healthy.
There are skis which explode left and right in any circumstances. Most likely for a reason. These often are in the cheaper end of the spectrum, but not always.
There are skis which have gained a reputation in being more durable than others. Most likely for a reason. These often are in the more expensive end of the spectrum, but not always.
There also are people who take care of their skis in every possible way (maintenance, damage repair, and practically everything the ski sees when it's not skied).
There also are a shit ton of people who abuse their skis on and off the hill and do everything in their power to lessen the longevity of their skis while also bitching about the shitty quality of their gear on the internet.
There's also a ton of more delicate variables in this, but even these few parts of the equation can get you very different results.
