I have used the super blade twice now, and the shaves are just super ;) .
If you make a mistake with a super blade you'll likely scar yourself for life, but on the plus side it just glides through my chin hairs like a hot knife through soft butter. And that's somehing that no straight (not even the lynn honed one) has ever achieved as effortless as the super blade.
It doesn't have the same 'niceness' to it as a real straight, but the results are awesome.
