The shave problem this mental midget (at least on the weekend!) is dealing with: nostalgia versus a better shave. I had just about made up my mind on next week's set up, then began to worry about the shave quality. My shaving notes from last summer, when I compared my Slim to the Karve for 2 weeks, showed that I consistently had minor irritations when using my Slim when getting the same closeness. For 2 years, my Slim was THE razor. I love it, it looks cool, and I like to think of all the men back in the 60s who may have used one before going to work at NASA in order to put a man on the moon! But on the Karve's first outing, I noted that the shave was as close or closer than the setting I typically used on the Slim, but felt mild and irritation free.
It boils down to me getting cold feet, I think, and not wanting irritation during a busy week with long, hectic hours (I get to work Black Friday, but that usually doesn't impact pharmacy too much, even when I did time in Wally World drug land). But this will be what I call my long week. So now I think, maybe push off the Slim to the week after. Another voice in my noggin says "life's too short for bad shaves, even if you love that razor!" And I tend to agree, mostly, which is why I sold off so many razors: why use a known biter when I can have a relaxing, drama-free, great shave with a lovely razor?! What problems to contend with, right?!
YMMV. Ain't nothing wrong with using the A plate.
