After a bunch of research, I've been using Avery Nano and Xpel patterns. Excellant film, but expensive. I learned long ago however, that you ALWAYS get what you pay for when your stickin' something to cars. Xpel is great, good tech support, but expensive. I ordered a 3m template collection to see if it's any good. It wasnt too much $. I will post comments on that once i get it.
