First off, I just think wearing ID is such a good idea. I live alone and generally ride alone, so I really like the idea that I can be easily ID'ed. And I am so sorry about your friend.

I have the original style wrist ID. I initially bought the ankle strap but it bothered me because if I wore it loose, it moved up and down on my leg when I pedalled. And if I wore it tight, it felt like it was squeezing my ankle.

Only complaint about the wrist ID is the tan line. Other than that, I love it and I don't even notice that it's there. I have more detailed emergency info in my seat bag so I had them print "Emer Info in Seat Bag" on one of the lines.
