I'm not sure it makes much difference assuming I take my left foot off the ground, pivot to let my foot go out a bit a little as I push sideways with my right, land with my left foot in it's new position and then follow with the right. I can see if my right was pointed in to the left more it'd be hard.

Perhaps I also naturally let it pivot out without meaning to often since my coach often reprimands me for letting that happen. Circling left is not something I guess I practice often as we only have one southpaw in our gym and I don't spar him more than once a month or so.

Do you see it being a lot easier with your right foot pointing out initially rather than pivoting as you are moving?
