That's what I'm thinking. Too be honest I'm thinking of getting some Nexus 7000s as used Nexus9000 in my size are hard to find. I've not heard a bad word about the blades either.
I think your best bet is going to be converting these and buying new Nexus skates, or, finding an older set of used Nexus skates, and having those converted. Otherwise you're basically staring over with skate fitting.
