...i've tried researching this but to no luck, so i'm asking you all! thanks
Seems like you did a poor job on that research. Anyway, the inserts is'nt the important thing really, though EST only works with ICS (which is general knowledge) and can't be used by any board. When doing research on something like this, dont just type "Bataleon jam best binding fit!", or somthing similar. You gotta do research for real dude. Read discussions about other boards and bindings and it will all fall in to place after a while. Happy searching!
Otherwise you can just go buy some bindings, they all work, usually.
