My recommendation is to go here Sample Packs

buy a sampler pack and see what's the best for you. I personally love the blades that you are looking to buy but just becuase its right for me means zip for you. My face is so forgiving that I could do this job with the broken edge of a glass bottle and it would come out great. In fact I have done that, came out great. Shaved with a common kitchen knife also came out great. The reason that we don't shave regularly with the broken edge of a glass bottle or a common kitchen knife is that they are weighted wrong dang thing kept rotating.
