Known as Snow Crabs, the Kreuzspitze binding toe pieces are some well-built pincers. The RS toes have strong steel springs and don't come with crampon receptors. The GT 2.0 toes have similar action but come with the receptor. Both feature a smooth locking mechanism with multiple notches for new versus broken-in tech fittings. The toe pieces seem to work especially well with La Sportiva boot soles, Kreuzspitze's Italian brethren.
I have a pair of spare SCTT heels that that I would like to get the toe pieces for. Any reason why I should not choose the RS (titanium) versus the RS-A (steel) version? I really don't care if they are something like 6.75 grams lighter, just like the color better.
Hey Karl, the toes are actually the same with a different color scheme. The U-springs in the heel offer the option to go with steel or titanium.
