I own the Model 20 and 28 type IAA Sumostance ladders. I'm not so sure about the accuracy of "hyperlight". The Model 28 is a pain to carry and position by myself. But then again, I'm 68 years old and I have never been super strong.
However, I wouldn't want to be climbing on any other ladder. They are easy to extend and take down, and adjust the outriggers for uneven ground. The wider stance has to add additional stability under any circumstances. A good investment in safety.
I wish they had a 12' model.
