When I first started, I couldn't get a close shave with a Tech. A year or so later, I pulled it back out and was surprised how much better it had become. Since then, of the dozen new and vintage razors in my rotation, I reach for the Tech the most. Once you've got your technique down, they give an effortless and comfortable BBS shave. I find they work with most any blade for me.
For what it is worth, I found that my shaves improved dramatically after shaving with an open combed razor for a while. I found it was easy to determine proper blade angle by looking for tracks, or better yet, lack of them, left in lather as I shaved. Once I became accustomed to holing the OC razor at the correct angle, my shaves were much better when I went back to those with a safety bar.
