just so were talking about the same thing, this is the old deadbolt 13, with the same toe as the 15 and 18:
this is the new/current 13 with the same toe as the padlock series(however the padlock series has a different heel than the deadbolt, the deadbolt 13 has the same heel as the upper deadbolt series.
All in all, If you really want the more durable binding, you could look for the old deadbolt 13, you could buy a deadbolt 15 if you are in that din range, or you could buy a Salomon STH 12 Driver because that has a really good toe.
by the way, tyrolia (makers of 4frnt, head, liberty, amplid bindings) are putting a different toe on the 15 and 13 bindings. Since it is summer and you probably wont be skiing for a while, you could wait for that to come out and just wait and see how other people like it.
next years toe:
