Replying to Is there a noticible difference between fks and px series?

don't really know much about the advantages of the turntable heel on the fks, but i want new bindings and i'm kinda undecided.
1. do fks release in any ways that would be an advantage to freeriding, that the  px series  (NON-turntable heel) can't?
and
2. whats your opinion on pre-releasing between these 2 bindings?
andddd
3. basicly, is one better than the other?

i know fks would be a bit more durable, but also heavier.  searched that.
help me out here?
