Totally agree with zzzz. I just add that Pilots bindings are *changing* the balance point of the ski, because they add weight behind the balance point. This is not much of an issue with skis, *if* they have been correctly screwed, a bit more rear to compensate that added weight. Otherwise the tail is likely to drag here and there. This is a major issue with (short) roller skis where the rear wheel will drag a lot. I've read some Italian increasing the spring tension inside the Pilot as workaround.
I moved back from Pilot bindings to Profil bindings on 2 out of 4 pairs of skating skis. For good.
Pilot boots (even the ones ("pro") whose bars are more rear) fits perfectly on Profil bindings. You may have to cut horizontally the top of the bumper to make it like it is now on brand new bindings . Because the nose of the boot is now engaging over it.

Note that very old Profil model whose locker has higher shoulders are not compatible. That's the reason you may read different opinions on that matter.
Should Salomon be deciding to make Profil bindings and Pilot boots totally incompatible, I would entirely move to NNN....
