Why the Jester Pros instead of regular Jesters? I've got both FKS 140s and Jesters and think that each have their advantages and disadvantages.
On really wide skis, 120+, I like the jesters because of the wider mounting pattern, also I find it easier to hike with them in the park because the heel is a lot easier to release in my opinion and the flat front is nice on your shoulder if you are carrying them.
That being said, I think the FKS might have a little better boot retention, although I have never really had any prerelease problems with my Jesters.
Just my opinion and unless you need the 18 DIN (seems like you dont because you are considering the 140s) I would just get normal jesters because they have a sliding AFD plate and the Pros dont.
Good luck!
