Replying to ON3P Filthy Riches vs Line Chronics

90% of the time I'm in the park and ever so rarely go out west so most of the time I'm in the park hitting rails and some jumps. I like the playfulness in a ski were I can mess around on rails that are flexy but at the same time a little stable. With the FR skis my buddy who is selling his pair asked me if I wanted to buy them and not sure which ski to get. I know that FR are super durable when it comes to park and want to know how line chronics compare with durability. I am also wondering which ski would be better in the park that would be fun to ride around and learning new tricks and how flexy chronics are.
