That is why I tend toward the Trac II if I wish to buff because the head is fixed. Blade buffing with a moving head adds a lot of complications.
Exactly why I shouldn't be stupid enough to try advanced techniques at O'dark-thirty, with only one cup of coffee in my veins. I think the Gillette Twinjector would be good for buffing, since it has a fixed head. Plus, it's pretty mild.
I like the Atra, as far as cartridge razors go. I also like the Sensor, but I won a lot of razors on Ebay last year, and the Atra was thrown in by the seller. Then, I happened to find some packs of rebranded Personna Atra carts on clearance at Rite Aid. Since they were cheap, and I just happened to have an Atra, I bought them. Turns out, I really like the ASR carts. Since I don't have any fresh carts for my Sensor, I use the Atra. I need to order some Triflexx carts for the Sensor, and some Atra carts from ASR. Back on topic. Never tried a Goodfella razor. Would like to, maybe. Dunno. I did some blade buffing today with my 1969 Super Adjustable and a Derby blade. No blood, this time.
