We bought a Twist 2 lightweight version to replace our Aquamarine K2. On one of our first trips out a light gust of wind flip it over on to a 1/2 inch blunt stick and punctured it. When i looked at the specification they reduced the weight by a 1/3 rd but reduced the strength by 2/3 rd. In Europe these are marketed under the Gumotex brand and we have 2 of their Solar 410c. They are absolutely brilliant although an improvement would be drain holes
