Since you just bought a Futur, I'm guessing you wanted something very different than what you already have. First of all though, don't worry if it's not a good fit, since those things sell quickly here. If you're lucky, you may even get 30 cents on the buck! Nah, I'm teasing.....you'll easily sell it for about what you paid for the thing.
Anyway, what's your favorite DE of those pictured? Which one gives you the best overall shave as far as comfort and how closely it works. That might be good to know as far as suggesting the next addition to your shaving arsenal. Hell, you already decided on the Futur, which I understand is a different animal than most other DE models. I sorta doubt it's gonna shave like the various other designs out there. Some people love em, but i can't tell you anything from personal experience.
How long you been using a DE razor? If it's less than a month, you're making things really hard on yourself. Those razors take some technique tweaking, because they don't all shave the same. Trying to constantly adjust the angle and pressure is too tough for someone new to this type of shaving. The main thing when starting out is to stick with the same razor for a while, otherwise it gets nuts.
Heh, I can recommend my favorite razor(s) to you, but it wouldn't mean much. You gotta try each of em yourself till you find a good fit. Might take a while or it might not......it's a trial and error sorta thing.
I look forward to hearing your opinion of the Futur,
Martin
