Nice write-up. I will say though it's important to change it up every once in a while. I when I started lifting I was doing almost exclusively concentration curls figuring that it was the most effective exercise. It worked for a bit but then I plateaued for a while. I didn't really break it until I switched it out for barbell curls for several weeks. Just make sure you are really putting the effort it to maintain correct form and not cheat when you do them.
