I'm one of those lucky people who get on OK with Feathers. I find them ruthlessly efficient, but you do have to be very light with them - no pressure at all. I also manage to get about 6-7 shaves out of a blade, but then I do soak and soften my whiskers well. I use them in an iKon open comb razor which gives a very efficient, easy shave with no irritation. However, I do find going against the grain is a certain recipe for redness and rash for me.
I'd advise staying clear of against the grain shaving unless you're really happy with it - ingrown hairs are much more likely.
