Somewhat more superficial question:
I got a couple RK-TRS-Xs in the mail a couple of weeks ago and received some long and thin numbered rainbow labels with them, but I'm not sure what the use would be.
They are numbered 1-10, with two labels for each number, and then two i1 and i2 labels. I have no idea what they're for.
Thanks!
