WittyCongA quick search would've lead you to multiple posts about armada durability issues of late specifically with sidewall blowouts. if you are using them as park skis I wouldn't expect 90-100 days out of them before they blow apart. And I wouldn't expect the warranty department to help you out if you do end up blowing out a sidewall and delaming. For heavy park abuse I'd recommend a more stout ski like a k2 poacher or ON3P. same with the TWs, I'd go with the chronic 94 if you were going to go with a line product.
I have multiple homies who rip 60+ days in the park on the old arvs. The new arvs are even more durable with the 3Dwedgewall technology. Personally I would never recommend any line product if you are looking for a lick of durability, same with k2, and you don't have a chance with k2 warranties. ON3P are widely regarded as the most durable, well built park skis out there, multiple homies that ski park daily are still riding their 3-4 yr old ON3Ps. I have skied faction in the past and I have broken 1/3 pairs over 4 yrs so, pretty happy with that and I was able to get a warranty. I just bought the arv 94, and plan on skiing it only in the park if that helps answer your question.
