I did a sequence in class that caught my interest, running through a similar sequence twice both times resulting in a 'side angle namaste twist', but gradually increasing it's intensity by changing which leg is forward while twisting in the same direction. The sequence:
1: Down dog, step through (left), crescent lunge, twist to the right with hands in namaste with arm on shin
2: Down dog, step through (right), crescent lunge, twist to the right with hands in namaste with arm on shin
3: Repeat opposite
I find this interesting as it may deepen the second round pose by doing a weaker variation first, preparing the body.
