flex for stiletto i would say 4. 1 being softest and 10 being stiff.
It's what my girlfriend uses for her burton lux and she doesnt have any complains about it. It's comfy easy to get in and out and it has easy adjustable points (high backs, straps, etc)
If you are just learning i'd say don't go for a stiff pair yet. Go with something a little soft for easy control in turning. I haven't seen any of the other bindings you have listed but i'd say the Stilleto would be a good choice.
