Durability? No, I didn't, but I didn't fly the new ones much. I bought a package, but wound up selling most of them to another guy here, since I don't like them much.

The folks at MAS know combat guys buy a ton of props, so they are keeping the GF/2 in production in some sizes. I just got a dozen 10x4's for limited B, and 2 dozen 9x4s for example. But I doubt you'll see many hobby stores trying to carry both types.
