Replying to Look P12: Lifter or..?

I guess this was already discussed like 1000 times before, but i honestly havent found anything. Yeah yeah searchbar hates meh..
So the thing is, i can get some Look P12 Lifter from my local shop (yes the 04-05 Pivot ones Not the PX), but im a bit concerned with the Lifter tag.
Whats the Real difference between Lifter and Jib models? Can i just mount the binding Without Lifter? Is there any difference between "Lifter mounted without Lifter" and Jib then? And whats the difference in height with and without lifter anyway?
Or should i just screw old stuff and go buy some Griffons/Mojo15/whatever else?
