My advice would be to take 6g of pure BA, see how that feels.
Then take your WF+PW, see how that feels. And add accordingly.
Any answer I give you would be giving away too much info.
But I will say this, a full serving of WF and PW has a hefty dose of BA. I personally wouldn't bother with the extra BA. But if you want, just test it out, see what combination gives your body the best results.
