i have them! rad fun super playful ski. they aren't suuuuper soft, (invaders, watchlifes) they definitely give a little if you push them hard. I LOVE them on rails, mounted them dead center and it's perfect. they are definitely better than my watchlifes on jumps... they are definitely soft enough for tons of rail work, but they have enough stiffness to be stable outside of the park
that being said this is the second pair of surfaces that i've thrashed to death... buy armada or something that won't fall apart underneath your feet
