Thanks guys! I really do like my investigator a lot. It is really small. Small enough in fact that I probably would have been hesitant to buy it if I'd realized exactly how small, but it is actually quite comfortable to write with. I'm sort of on the fence about whether or not to add O-rings, but it'll likely see some pretty heavy use this week that will help me decide. I'm especially glad that I opted for copper over aluminum. The added weight helps the writing experience for me (I know I'm weird, blame writing quirks on being left handed in the western hemisphere).
Also, thanks for the picture tips N2K! I need to practice finding better light, staying out of the shadows, and likely trying to stabilize my phone a little better and maybe I can produce a few better quality pictures from time to time.
