I hope to learn the same :)
One issue with using many blades with several different finishes is that each takes diff technique. Some allow but don't require pressure. Some will cut you a new smile if you use pressure. Several times I've thought that sticking with one or two blades would help me learn faster.
The edges that demand perfect technique can be interesting, but are rarely the more pleasant shaves. That's not an argument for lousy technique. If I used an extremely demanding blade all the time, there are lots of strokes I never would have tried. Having tried them with forgiving blades has allowed me the experience/practice to do them with demanding blades. Now good technique w/ a forgiving blade still gives wonderful results. 'Very satisfying.
