Difference in AF 8-5-8 and normal Gran Reserva?

I smoked an 8-5-8 yesterday, and although it was a decent smoke like any other AF, I couldn't really discern any difference between it and a normal Gran Reserva. The wrapper seemed as though it was a bit darker, but not much. Is it the same filler wrapped in a sun grown wrapper?

I don't think there is any wrapper difference in the 858's and the other Grand Reserva's. They have the standard camaroon and maduro wrappers that are typical of the line.

Any difference would be in the blend. The Sun Grown version has a very different flavor.
