Shaved with my English Flat Bottom Tech on Wednesday. Great shave. So close and comfortable.
A Flat Bottom Tech (and of course a Hybrid) are definitely on my "keep a look out for" list.
The mid-1950s English 'Heavy' Tech (63grams - see the 1956 #24 set at the @mr-razor site) is also quite good.
I have a 50's model Made in England Tech that I'm told was for French distribution that weighs in at 57grams.
