The 1400 is a good compromise that boils a reasonable volume of water, but isn't needlessly heavy. The frying pan doubles as a lid, reducing the time it takes to heat the pot's contents in cold or windy weather. Putting the cook set in the stuff sack was a challenge, especially after stowing an MSR Whisperlite stove inside. I learned to do this more easily by setting the cook kit on the ground and sliding the stuff sack over it. This sure beat trying to drop the kit into the sack.
The Prolite 3 is lightweight and comfortable, exactly what hikers need when staying in the backcountry. It's only downside is one that it shares with all air mattresses. Although durable, it can't work miracles, and an unnoticed mesquite thorn can ruin your evening. Check the ground on your hands and knees before putting down your tent floor or ground cloth, and don't forget a repair kit. Fortunately, the latter works quickly and efficiently, even in the field.
