uneven split silks double footlock:

this is the same as the regular split silks double footlock, except that the second footlock is tied at a different height from the first. this changes the sorts of moves that it's a useful starting position for. it can also lead to variations in tying the locks-- for instance, after tying the first footlock, bend the knee of the tied leg and slide down until you're sitting on that heel, as if to go into a side layout; this gives a very stable position for tying the second footlock.
uses/builds on: single foot lock.
