Honestly it's been a year since I played low level THM/BLM but from what I remember I didn't have a chance to use Transpose twice in a single rotation.
Also, I prefer the fact that when I cast Fire I from whatever Umbral state it was that I rather do it there than hardcast it in Astral I (takes longer, more MP).
And you most probably, almost always, would probably find better results that you hardcast FIRE III when in umbral. Don't use Transpose from Umbral to Astral if you have Fire III. Use transpose when you have Blizz III if you messed up your rotation xD;
