Replying to Cant decide chronics or invaders

I have a chance to get either some chronics or invaders for cheap and i cant decide what i should purchase. chronics would be dope for jumps and everything but i have do already have watchlifes. invaders would be a cool jib/rail ski but they might wash out alot of jumps since in 185lbs. im 6' and im thinking either 176 chronics or 178 invaders if anyone wants to tell me why i should get one over the other or have suggestions on sizes post away
