I don't necessarily buy into the theory myself but it sure does seem to have some merit. I do like the idea of somehow using that spinning energy, once the arrow contacts the target, in a positive way. And, to also bring in the "heavy/light arrow" argument LOL, the spinning energy, if utilized correctly in the crimson talon theory, would have much more effect with a heavy arrow. I wonder if spine strength would also be a factor. Seems like it would, with the torqueing of the arrow and all.

It doesn't seem there could be a realistic test of the "pull through' effectiveness though. Even on game animals, who's to say which pass thru was more effective or if one pass thru is more effective than another given that they hit the exact same spot.
