I've got a miyabi 600 mc with SG2 steel and I really enjoy it. Once you've set the edge you want on it (for me I changed it to more of a 80/20 edge) it resharpens fairly quickly. It takes a keen edge especially when i finish with a loaded strop. It reacts beautifully to a borocilicate rod and gives me a hair shaving edge in a pro environment for a good two weeks before i choose to resharpen. I like SG2. On the elites I think it worked well with regards to the butchering style knives they have like the honesuki.
