I also started with a vintage Kropp recently. I considered my options and it was going to be iether a Dovo or a vintage from a reputable seller.
It's a steep learning curve as there are more things to consider. For starters, you have 3 inches of very sharp metal sliding down your face and if you don't concentrate you will cut yourselve.... that's how I got my first nick, I was shaving under my nose and focusing on that alone, the tip of the blade cut my cheek, nothing much but still.
It's very rewarding when you get good results but it's a very different experience to shaving with a DE razor.
I went for the "pro shaving" experience at Geo Trumpers to see how that would feel. I couldn't draw a good conclusion though, they use a shavette and that felt very much like a DE razor. Still, a very pleasant shave and I nearly fell asleep lol. result wise was a little disappointing, I get a closer shave with any of my DE razors, although I understand why they don't shave ATG.
The maintenance of a SR is wearing me down, something I need to build into my routine. It seems I'm stropping close to well enough
at least my face tells me that, but stropping is tedious to me atm, so I'm hoping I will get used to it.
One more thing, I listen to the knowledgeable people here so I'm giving myself 100 shaves to learn the skill. I have shaved 11 times so far and I still need to clean up with a DE razor. I have high expectations so I guess I'll be cleaning up with a DE for quite a while yet
