If you're looking for immediate damage, then yes...but you can always stagger. PNGxx1,1 leaves you at -1 and PNGxB1,2 leaves you at neutral. Unless they're ready to armored reversal...thats a free d1 check (or, if they're respecting the d1, go right back into) b12 at which point ferra is on your back and you can either OH toss for plus frames and more pressure or you can PnG again. While ruthless gets the most immediate damage...that's not what the variation is about. It's about pressure and making them scared to press buttons. I rarely open up knowledgable opponents with PnG, I have to use frame traps and the mind games that accompany the cancel pressure.
