As a fairly recent newcomer myself (about 4 months in), I wanted to share a few lessons learned and insights I have had during my starting experience.
In another thread a member warned to watch for hubris. It sounds like you had a good first experience and when I started, I had a number of very good shaves. I am sure part of this was contrast effect from what I was doing to my face previously. So I thought I had this this down and did not pay attention to technique. The outcome was predictably ingrowns, razor burn, and nicks.
From your short post, it sounds like you are patient and thoughtful about your approach. This will serve you well. Take your time, do some research, and ask questions. There is a wealth of information that can help you including the fine gentlemen on this board (as you have already discovered). If you have not already found them, I recommend the Shaving Tutor videos by fellow member Mark, aka mantic59. They provide good information and are entertaining to boot.
I would recommend slowing down on switching blades unless what you have is intolerable. If you have read around a bit, I am sure you have seen YMMV (Your Mileage May Vary) in reference to different blades. This is what JayTrek mentioned above and others have hinted at. The way a blade performs for you is influenced by a lot of things, including but not limited to the particular razor you use, the corseness and thickness of your beard, and sensitivity of your skin. If you move around too much early on, it is difficult to tell if the issues you are experiencing are due to the blade or your technique. I started out with Merkur blades and had good experiences with them. Others think they perform like a rusty lid to a tin can.
Having said that, certainly take Murray up on his kind offer to send you some Crystals to sample, whether you go with these for now or save them to try later. One of the great things about this community is the generosity of the members to not only share their knowledge and experience, but also share products to help us newer guys get to a better shave.
