PTWF's doublestrike bonus is universal; it doesn't matter what melee weapon you have equipped nor which combat style you use. I'm guessing that will still be the case post-update.
PSWF requires the SWF feat; since SWF will do nothing for animal forms post-update, it hardly makes sense to enable it for animal builds.
I'll reiterate my request for a Perfect Natural Fighting ED feat, coupled with a respectful request to maybe consider making the Natural Fighting feats less terrible. If it's not too much trouble.
