Hiya,
Nice review Ian,
I gotta admit those things pique my interest a bit. Having used injectors for years, I have a strong appreciation for that type of SE razor. There's a few things I'd have to see about before buying one though.
What the Cobra looks like to me is a very heavy injector with a wide head that only takes a Feather blade. I'm a little spooked about using any razor that's about 100 grams or so, especially with that blade. The head width I could get past easily enough I think.
I like a Feather blade, but not in all razors. I'm afraid it might be too much and I'd have no other option. It looks comfortable to hold, but I'd wanna see for myself just to be sure.
Heh, if you ever feel like lending that nice looking piece out, I may have one or two interesting razors that you might like to sample in exchange.
