Not yet on the button. I have a lot of razors in that efficiency zone.You know, it depends!
I got my last 2.0 with that closeout sale that Italian Barber had which made it a no brainer. It was ridiculously cheap for what it is. But at full price I would probably just stay on the 1.1 considering what you paid for it too.
But.. you know I have to try them all which means I personally would probably break down. That's just me though, not trying to enable!
They are different: The finish, handles (long vs. short & fat), balance and a slightly different shave.
I know you've been asking for quite a bit which means you're at the point of almost pushing the button!
Your call though!
