Replying to Are the pivot bindings really that good?

Hey there, I am looking for new bindings and I was told that the look pivot or the rossignol FKS are super great to avoid injuries.

I was thinking about getting those because I have a little problem on one of my knees.

However, some people told me that they are not as good as they say.

I like going fast and playing around, and I ski most at the park and powder.

Do you think that it is worth getting the pivot or the FKS? And if not, which binding do you recomend for me?

I would apreciate any opinion!

Thanks
