Don't stress about finding the most suitable blade for YOU. Improving your technique and consistency is much more important. I would even suggest that you choose a blade and use the same brand for the next month whilst you work on technique.
This is the advice that I took to heart when I started out. I was finding it difficult at first to resist the temptation to keep switching blades in the search for the perfect blade for me. I found that staying with the same combo for a month was invaluable in developing my technique.
