It's really easy to get carried away. I'm no role model here, as I bought three DE razors right off the bat, and a bunch of blades without knowing what kind I'd like best. With that in mind, why not take a few shaves with your 34C first to see how it works for you (not for someone else)? You can get great deals on blades by buying in quantity, but maybe sample a bunch of different ones before you buy 100 packs. Just my 2,000,000 µ¢.
