Appreciate your comments and advice. Like you, I also shave steep unless the razor geometry prevents that approach.It is well balanced and you might not mind the weight or notice it as much as you think. I even think the weight is a factor in the efficiency - more momentum behind the blade edge. But you do need to be conscious about using a light touch and not adding pressure - especially if you are used to something like a Vector head.
I remember my first shave with the Sailor, and at the time I was favouring lightweight, slim razors like the H&S P076 Ti or the SS Vector. I used too much pressure, held it too tight because it was heavier than my other razors, and I had the Sailor on setting 4 the whole shave - altogether it was too much. Second shave, though, with the same Kai blade, I took care to use a light touch and hold the razor more lightly in my fingertips, low on the handle, and I dialled down to 3 for the second pass and 2 for the third. It was the best shave I had ever had, and still memorable as one of my most perfect, longest lasting and comfortable shaves. I still always use 4 for the first pass because I love to get a really close cut with the grain - it seems to make the rest of the shave easier.
I think with the Sailor it doesn’t feel unwieldy at all, and you can just trust that the momentum of the head will do the work for you. I think that’s the way to use it. Imagine you are driving a Rolls Royce - it’s heavy but you’re relaxed and everything is calm and easy, you’re steering with your fingertips, though it has masses of power.
I shave steep with it, by the way, and that works for me. Like with a Wolfman WR2. That probably also makes the razor feel less weighty since you are not lifting the handle, you just let the razor hang naturally. And it probably makes it easier to not press the razor onto your skin than if you were shaving neutral or shallow. For that reason I always shave steep with high gap razors.
The Sailor promises to be a very interesting experience.
