How true! But I dare not call climbers UL- they "UL" thier camping equipment so they can carry all that climbing gear! Climbing like backpacking has a range of levels. Elite climbers choose to reduce gear and comfort, at significant risk, in order to achieve thier goals. They are betting on their ability to go faster with lighter pack. Sometimes they get done in by that. The weekend recreational climber seldom is willing to take that risk or be that uncomfortable. Each, however, have gear appropriate to their goals and personal risk assesment. There is no right or wrong- just appropriate.
