I've used a Mountain Hardware Trango 2 for the past 20+ years and absolutely love it. I've finally had to admit that my old legs need something lighter. The Trango II weighs just under 10lbs. I know the Optic (6lb3oz) and Talus (6lb1oz) are still on the heavier side by today's standard, but my daughter and I like the extra room they will provide. The Optic is 37sf and the Talus is 38.9sf. They cost about the same.
Comments on their durability/versatility/other issues or make other suggestions greatly appreciated!!
