Hey Jon, the shape of each boot is different enough that Dynafit had to make separate tongues for each model, however with a bit of modification I have seen a few people cross models and brands with success. Keep in mind, any modification you do to a tongue will void all kinds of warranties though and I don't necessarily recommend it.

Hey Richard, you got it, those should work just fine unless your ski is particularly thin. If it's a thin ski you may have to grind the screws down to get them to not dimple the base when you screw into it. Otherwise you're safe to use the 12.5mm screws.

Hey Paul, these crampons have a Dynafit style compatibility and don't fit on Plum bindings. 75mm will be fine on a Backland UL 65. If I were you, I would check out the Plum crampons.

Hey Brian, yeah that is an issue with the older Radical heel pieces unfortunately. There are 3 iterations of that heel piece now, the original, an updated heel piece (reinforced so it's a bit stronger), and then the latest iteration that has addressed this issue even further. How old are your bindings?

Hey Brent. They're splitting on the full size (27.0/27.5 are the same).
