Welcome to the board!
I\'ve seen posts where guys said that PI didn\'t mix well with APC. I tried a really small batch, 14 drops of APC and 6 drops of PI, but I didn\'t notice any separating of the products.
I\'d still go with the NPA. It always mixes well, and there\'s the added benefit of the secret ingredients that PI doesn\'t give you.
The only way you can go wrong with NPA is using too much of it or using it with inadequate fragrance cover. For these reasons I recommend increasing the APC content of the mix (from the standard Jambat #1 ratio of 7:3) to 3:1 or 4:1, APC to NPA.
The phero scent of NPA will outlast the fragrance of APC even at these ratios, but at least you\'ll be giving the APC a fair shot at covering NPA\'s A-None aroma.
