OP, I haven't tried those ones, just the later types. If you haven't used one before go carefully - it'll probably be quite aggressive and I find them easier to cut myself with. That might just be me though!
There are some great injector blades out there, they're just tricky to come by cheaply. I have tried the bad and the good:
Personnas - vintage and modern, including a twin blade design (distinctly average) - vintage PALs (terrible), Schick Eversharps (not very good). However, Gillette Platinum Plus (I think the only injectors ever made by Gillette, which was back in the early eighties) are superbly smooth and sharp to the point of lethal and the modern Schicks from the US are very good (buy on Amazon) but with postage from there you're looking at a pound a blade. I did manage five very good shaves out of one which is better than most DEs by about two shaves.
