I am thinking of getting either P74 or P83 to pair with NPA to soften the none. Which one is better and what dose?
If you want to moderate NPA, P74 is the only one of these two and it does the job well as NPA’s overtness keeps P74’s unwanted tendency to friendlyness nicely in check.
As for dose, you really need to do some testing but with 2-3 sprays 1:5 NPA, I’d keep the P74 below 30mcg to ensure its moderation/closeness/bonding properties don’t veer into the dreaded best-friend effect territory.
P83 is still a superb secondary for its physicality/space closing/disinhibiting properties for the above but its not any kind of moderator/softener!
