Replying to G3 Zed 12 or G3 Ion LT 12 Bindings?!?

Can't decide which one to buy. I'm contemplating on spending the extra 50$ to get the Zeds which would save .5lb per pair but apparently, the heel piece wears out and slides backwards when using the risers. My Dynafits do that and its annoying. I feel like the Ions are more durable. Does anyone have any insight? I'm not buying any brakes for either of them.
