I hope that future podcasts on the subject will contain greater focus/editing, better articulated points, and specific gear. I would have found a little spirited debating refreshing as well.
For instance, on the issue of safety, while I agree that a lighter weight pack itself contains a safety factor, other important points were not mentioned.
1. The heavier the pack, the greater chance of sprained ankles, falls, etc. - followed by all the problems of dealing with injuries carrying heavy packs. Any additional first aid in a heavy pack is unlikely to fully compensate.
2. Some light gear is inherently more foolproof and thus safer than their heavier counterparts. Alcohol stoves with no moving parts are more reliable, as are foam pads as opposed to the more common air mats.
3. Longevity is sometimes offset by a much cheaper price, such as with packs. I thought the talk of the extreme fragility of lightweight equipment was quite exagerated.
After all, ultralight was pioneered by some of the longest distance hikers around, and their gear needed to hold up. While my G5 pack might need some carefull care, my just under 1 pound G4 is quite rugged, as are my tarp, alcohol stove, foam pad, sleeping bags, and titanium cookwear.
