For what it's worth, they are CAE arrows, not AFC. Both companies used a similar sizing system, and that is why the size designations are the same.

I had a bad experience with these arrows when they first came out, but in all fairness, that was close to 10 years ago. I've heard that they have improved quite a bit by now. Knowing how 5-shot tests and analyzes everything, if he says they are good, you can bank on it!
