The THALLS are more park oriented so you might like them a little better. In terms of flex, the chronics are basically a cross between medium to stiff flex all around, while the THALLS are stiff in the waist, but buttery on the tip/tail. I don't know much on the durability since I don'y own the skis, but I've ridden them multiple times. You might like the Armadas more since you are basically all park. The chronics are still dope for park though, although they are generally an all-mountain ski
