Do you mean a suicide clutch? If you wanted to go foot clutch, I think it would be best to go with a rocker clutch. That way you can lock it and put your foot down at lights. Quite nice if you have grip problems in your left hand, and very trick looking if you can do it right. Or if you don't want a foot shift, you can always go for a jockey clutch, which looks very nice when made of brass.
After sitting in stop and go traffic for 45 minutes, my mind to always goes to the "I should have gone foot clutch" thought.
