Sleeping bag recs ?

[netllama]

I've got a long duration (25 day) camping trip planned for November into December in a part of the world that will be quite warm at the time (not anywhere in North America).  Most of the gear is being provided when I arrive, however I need to bring my own sleeping bag.  The only sleeping bag that I currently own is not going to work for this trip (its too old, too heavy/bulky, and not very comfortable).  So, I'm going to need to buy a new sleeping bag which is appropriate for the trip (ultra-light, warm down to around freezing, durable).

Apparently much has changed in the world of sleeping bags, and quilts are the new hotness, as they can either be a traditional bag, or, well, a quilt, depending on the temperature conditions.  This looks very appealing, as I tend to roll around a lot at night, and a fully closed bag is always constricting, plus I tend to overheat.

After a lot of research, I've narrowed down my options to the following three (in no specific order):

1. Katabatic Gear Flex 30F Quilt
   
2. Therm-a-Rest 32F Sleeping Bag
   
3. Enlightened Equipment Revelation Quilt
   

I'm hoping you fine folks can offer some input to help me decide.  Even if you've never used any of the above, if you have any opinions, I'd love to hear them.  If you have used any of them, so much the better.

I need to make a decision in the next 2 months or so, to allow enough time to order + ship before my trip.

thanks!
