I haven't actually used the 5/6 plate yet, but having used the other two plates, maybe I can at least give an opinion. I'm one of those people who started with the 2C. You know where this is going. Long story short; then I had to have the 2/4 plate. Then why not get the 5/6 and have the whole set. This system is fantastic. It will tame the harshest of blades, which for me is the Crystal. I used the two plate for that and it's BBS with two passes with no irritation. These people have totally figured out the angle, gap, and exposure geometry of a razor. My only regret is that I didn't start with the 6C in the first place.
