Make sure you have your model years sorted out. At least for 08/09 and now 09/10, the Peak 15/18 and Mojo 15/18X are identical except for the springs. I switched to these bindings last year, and I think it would take a stick of dynamite to damage them. They are heavy, but tanks. These current models all have the Aero toe and Race Pro heel. I believe in earlier model years, the 15-DIN models did not have that heel.
I am not up to speed on the older FF/Mojo models but I do recall that they were still using the diagonal heel as late as 07/08. It's a decent binding, but nowhere near as stout/solid as the race heel.

At first I couldn't figure out why tyrolia would make a 17 and 18 which are only one din apart, but i realized it's because the 18 is a real, high quality binding while the 17 is cheap shit.
I'm pretty sure it also has a wide din range so as long as you fall within the range i see no reason not to use the 18.
