Fei os?

I was playing my friend Larry the other day and he was using os Rufus u2. It was amazingly effective and the kick in the butt I needed to start using os’s. So I began thinking about vs non shoto if os would work with flamekick or cw. Can someone point me to or list some fei os’s?

If you understand how os’s work you can pretty much create ones to suit your situation.This thread has a few of them http://shoryuken.com/f273/lab-findings-243075/index3.html
