Replying to Dalbello flex advice

I’m considering getting the dalbello panterra 130 ID boots. I’m curious if the 130 flex would be too stiff for an average skier that weighs 163 ish. Also I’m aware that the boot’s stiffness is adjustable, but can you only set it to only 2 flex’s (soft and hard) or can you adjust it to everywhere in between and find a flex that works best for you. I’d appreciate it if anyone with knowledge on these boots could leave a response, thanks.
