Speaking of the Vortex, anyone know the difference between the A3 and A2 as listed on Smith's website?

Other than the obvious fluting, that is. Does the 10 degree pitch refer to the prongs (meaning they are not 15 degrees like a standard Vortex)? I've also read about some "super alloy" in the A3s, but that isn't listed anywhere. Finally, does anyone know if the flutes actually help with anything on the HALO?
I ask because I'm looking at pairing my potential HALO with the A3, should everything line up correctly.
