Goh's Sabaki Grab

Again, probably well known information, but if it helps somebody...

I've been using Goh's P+K, P+G grab against crappy CPUs who stand and guard. The range on this is good (comparable to his high kick, and roughly the diagonal of one square in the training room), and it seems to be reasonably fast. Is this the "correct" way of dealing with standing turtlers or will c-XPD be better?

I set Jacky (who I named "Holly" after WWF jobber Bob Holly) to fast getups with roll-into-screen and it seems that after the legsweep tsukame throws which do not end with punch (i.e. everything ending in u or d except uu and dd) a ground throw attempt is guaranteed.
