First, I think we should NOT group 154cm and CPM-154 together. In my experience CPM-154 is noticeable better and IF that could be gotten I would choose that. What would the heat treat be on the Elmax? It seems that Elmax at 59-60 is decent but at higher RC levels it is a monster as Jankerson showed. I have no problem with CTS-XHP.
I dont know about the rest of you BUT I WOULD pay an extra $50 for S110V.
