bwork_1Oh Vishnu’s aren’t durable? What’s durable then man? Only ever heard positive things about their durability.
Any brand that sells more than a few hundred pairs of skis will inevitably start having people complain about durability. Generally speaking, the more skis you sell to park skiers, the worse your reputation for durability gets. The reason? Park skiers break skis... and then go online to complain about it.
Assume, for the sake of an example, a 1% break rate and of that 50% online bitching rate. If you sold 500 pairs then 5 would break and only two or three of those people would come online to complain about it. If you sell 5000 pairs of the same ski, you suddenly have 50 broken pairs on your hands and 25 people online calling them out, and you start to build a reputation for skis that break, even though no more of your skis are breaking than the small brand, percentage-wise. Unfortunately, the absolute number of people who break your skis matters here, not the percentage of skis that break.
Disclaimer: Some brands and more often certain skis, have specific issues above and beyond this, Faction and Line have both had bad patches that they've acknowledged. Often there are huge variations within a brand too. A random example, but K2 Poachers had a great reputation for being bombproof, while the K2 Reckoner 102's had the opposite reputation at the exact same time.
To the OP: Vishnu generally has a very good reputation for durability for a reason, don't overthink it, the likelihood is your skis will be absolutely fine.
