Winter Variation is a subset for when your last layer edges are oriented in which you use your last slot to orient the last layer corners. This set is widely known by a fair amount of cubers and is very useful if all of your last layer edges are already oriented upon creation/insertion of your last pair. With LCEO, Winter Variation becomes an even more versatile solving tool since you can do it in any solve without worrying about the edges since you fix them right after.
