You can't be serious. If you've ridden any of them yourself, you'll know that most of them are pretty bomber. My Rubys have ridden over endless rocks, stumps, and been on multiple wipeouts, and I have yet to have any coreshots.
The Jibs are pretty damn tough too - although there have been problems, I'd deem it safe to say that it's a damn solid park ski.
Park boards break, thats how it is. When you sacrifice weight and flex for durability it's goona happen especially if your riding on a higher level. Fact of the matter is the Moment cats take input from their riders AS WELL as their customers and that will create a superior product. The Reno jibs are by far the sickest park ski I've ever ridden no bullshit and I come from a time where we used to oven bake twin tips because there was no such thing. Moment is only two years young, wait until this company matures and the world will see how legit Moment is.
