First, I'm sorry to hear about your friend.

I got the dogtag style for both my daughter and myself. It slips on easily, tucks into my sports bra, and doesn't leave a tanline. I put all of my contact info and brief medical info on the tag itself because someone here (I forget who, but she had something to do with EMT or ER or something) said that in an emergency situation, you don't want to have to rely on your personnel having an Internet connection, and they don't have time to go look it up anyway, especially if it could be right there for them to access easily.

And with the dogtags, you get to choose a graphic design to put on the back. I chose the female cyclist for myself, and a paw print for DD because she's an animal fan. I also got her the lime green silencer. She wears it every day, ride or not.
