If the head is low profile, nimble and maneuverable (Vector, Slim, Tech, B1 Standard), I use that razor and don't need a touchup razor.All your posts help. It helps that you're clear and that I have some understanding of what you like and why you like it.
How often do you use the Hydro-Magic to do any touch up work?
It's been a very long time since I used SE razors, but that doesn't mean I don't like 'em. I particularly like the Schick L3 and the Schick E2 open to clean. Perhaps my favorite AC platform razor is the DLC SS Hawk.
If needed, the Schick SE razors are (for me) excellent for touchups in those "nooks and crannies" areas.
