Then the next question is down vs synthetic.
Down is the only way to go for ultralight service, ie backpacking.
If you are going to set up a hunting camp etc, then synthetic won't pack as tight, and is heavier to transport, but provides better cushioning beneath you. We used synthetic bags in the years that we spent nearly every summer weekend up at the gold mining claim (and got drenched a few times), then switched to down as the kids and adults went off in different directions. Younger Daughter spent a month camped above the tree line (9,000+ ft) in the Sierras on a college biology project in 2005 and said her Class 5 down bag was ideal for that.
If you fall crossing the creek, or the creek rises overnight and runs through your tent (BTDT) then you can wring out a synthetic bag and it will still provide maybe a third the warmth of a dry bag. You sleep soggy, humid, miserable, but its not life threatening. And it will dry out after a few hours hung up and dripping. A wet down bag is like a soaking wet newspaper - you would be better off nude in the rain than inside it - it will cling to you and suck the warmth out of you. You'll never get it dry before the end of the trip.
Which is preferable depends on what you have planned.
