The Malavitas are very solid bindings and pretty lightweight. What I didn't like about them was the reflex disc which is very small and doesn't hold the whole baseplate on your board. if you lift up the heel part of the bindings when they are mounted, they will lift half an inch. Also they aren't very customizable.
If you don't mind your bindings being medium weight rather than feather, check out the Forum Shaka. Very similar to the Malavita but with a more solid disc and a movable heel cup so your foot will always be centered (which was never the case with my Malavitas). They have canting and the straps and ratchets are great. Also, they didn't change anything for 2013 so you can easily go with the 2012 model.
