Just tried my new NOS Gillette Alu Tech, with a Gillette SB.
Hot towel soak for for 1 min
RSC cream, Omega brush face lather
2 days growth and the little Tech couldn't manage, so quickly swapped to my Black Beauty with a 3 shave old Sputnik for a 2nd WTG pass.
Then back to the Tech for the ATG and touch up.
Most pleasurable shave. The little tech is a pleasure, just not aggressive enough for more than one days growth.
Impressed with the Gillette silver blue too!
