TOTAL NEWBIE here and about to start DE shaving. I bought a long-handled barber pole 38C (which I think has the same head as the HD?) and the seller threw in a Gillette British Tech (alu) for free.
Question 1: which should I start with?
Question 2: I've got some Derby's for the Merkur but which is best for the Tech?
Question 3: What's the difference between a SuperSpeed (which you lot all seem pretty keen on) and aluminum Tech? Is there much in it?
