Setup for leg trip

Been try to figure out how to setup this leg trip effectively... Most of my sparring partners who are well into their blue don't seem to take the bait. Any ideas?

lol, did you try a different cheese?

eye contact is key, you must maintain through the whole transition. If eye contact is broken then so is the sweep my friend.

Are you wearing the proper dress?
