This is my vote. Why scrap a sick binding over a defective strap. Upgrade and enjoy.
It's not that it is defective, it just doesn't work optimally with every boot. My 11/12 Atlas work great with my Rome Libertines, and it has the same Toe Cap as the SL. So yea, instead of getting rid of the whole binding or getting a new boot (we all know how hard it is sometimes to get the right boot), just switch up the toe cap. The other option is find one of the older Union toe caps, like off the Data or Force.
