Replying to How to decide on flex

This coming season I'm thinking of getting a new set of boots and one thing I don't really get understand why softer boots are often are preferred by park skiers, I like to hit big kickers, around 60 foot range and at the end of the season I was starting to spin them. I would think the precision and control you get from a stiffer boot would be better but a majority of people I talk to say softer is usually better. If anyone knows the logic behind why soft is better it would be really helpful to me
