Very interesting... I agree with Matt; I, too, own all the Primos videos for the last five years or so, and they've never mentioned it. Seems like a direct retaliation, if you will, to the MAD growl... They even use that verbage in their description.

And... it's the first Primos call I can remember which comes with a mini-DVD, though I may be wrong. I do like the combination of the snort/wheeze along with the growl... saves packing an extra call. If you're thinking super-aggressive calling anyway, might as well put the two most aggressive on the same platform.
