I am hiking the Fires Creek Rim Trail this weekend near Hayesville, NC. The temperatures should be in the mid to upper 20s this weekend per forecast. I am set on a UQ with a 0* Phoenix but my top insulation will be either a 40* or 20* sleeping bag. In your opinion can I get away with the 40* sleeping bag? It makes me frustrated just thinking about wrestling my 20* synthetic bag in my Osprey 58 Exos not to mention the stuff sack.
I am going out in the coldest region of NC this weekend (Banner Elk, GF Mountain) and the lowest temp per forecast is 33. I think you will be fine down to that. I am using a blue pad with 40 deg bag and good clothing. ie good thermals and some fleece. I think you'll be good to go man. Have fun!
I think all (or most) of your answers to this will be something along the lines of "everyone is different so you will need to test it out yourself" :)

Having said that... my guess is that if it is upper 20s then you'll probably be ok as long as your UQ is keeping you toasty warm but you will also need to make sure to keep the wind away from you or all bets are off. I have found that, for me, I need less TQ and need to concentrate on keeping the UQ side of things warm. But that's just me (see first answer above). :)
It depends on how warm or cold you sleep, but also, how bad would the occasional cold night be to find out? If you're worried about just a cold night, go with the 40* bag, if you're worried about freezing to death, then the 20* bag would be a better option.
If you sleep warm take the 40.
I am going with the 40* + my warm-up sheet. I think I can survive 2 nights.
not sure about your area of the country, but here in WI if it's going to be below the temp rating on the bag I go with the warmer option despite weight (and I tend to be very weight aware).
If you're a hot sleeper or have some additional clothing / down gear with you it might mitigate the cold.
Personally, I like a good night sleep, sleep cold and don't like to be cold. Kind of ruins the trip for me if I don't sleep because of being cold.
It only dropped into the low 30's and I was toasty with my 0* UG and 40* bag. I did have a therma rest under my feet since I use a Phoenix.
