My Tech arrived today so I decided to give it a try. Kai blade, Tabac soap and my usual three pass shave. WOW. You can feel a blade on your skin. I don't know if it more aggressive then my R41(2013) but it feels different. I got my closest shave ever with no irritation. Decided to use for month exclusively in order to master it and then try R41 again.
I suspect it will be a love story.
Congratulations Felix! Yes, the ST has a lot of blade feel to my face, but in a good way! I know by that feel the hairs are going down... After a while you might find you can do with 2 passes rather than 3. I use a 2 pass steep angle approach and the shave lasts longer than with my R41. I fell in love with the ST from my first shave with it. My R41 is getting dusty.
