In reply to anaesthetic:
If you aren't in a testing hurry I would definitely wait until the next PHD sale. I don't believe you will get a higher quality bag even at the non sale price, but the sale makes it less painful. There seems to be one every few months. They can also make them exactly to order for the diminutive climber
I have a minimus bag for mountain marathons but use it backpacking and bivvying as well, it is a wonderful bit of kit. And under 500g it's all I use above zero degrees.
