Replying to Dedicated Urban Skis

I was wondering if I should buy some cheap twin tips for urban skiing. I plan on buying the 2014 line chronic and 2014 armada Norwalk, but I felt like shouldn't use the chronics for urban because they are known for chipping and I plan on using them on a lot of urban rails. I live in pullman, Washington, believe it or not one of the best places for urban in the west (lots of big rails, big hills, about 3 feet of pow by Christmas). So what do you guys think? Buy some cheap twin tips or risk the integrity of my chronics?
