Trying to decide between this and the Mavericks 30. Will use only for summer camping. 3-4 nights at a time. Nor Cal (Napa, Calistoga, etc.) weather. Seems like the 30 would be more versatile for the mountains, but could be too warm otherwise?

Go for the 30. Its pretty easy to unzip your sleeping bag and let off some heat, but if you're cold - its more of a challenge to deal with.
