Sounds like you have very sensitive skin. I'm afraid I don't know of the best lighter razors and moderate blades. When I did use cartridges I liked the Schicks more. Cleaner cut and less irritation. Gillette used to be good a long time ago but it's pretty crap now. Gillette still makes blades for DE but they aren't remotely good, IMO.That's still too much of an issue for me. Hence the reason why I use the Gillette Sensor Excel (I formerly used the Schick Xtreme 3 disposable razor until the price got too high even for a four-pack).
I've never found anything that's as close as a Feather.
