Please allow me to clarify any misunderstandings - The cuben LightHeart Solo in CT0.6K.08 weighing 0.48 oz/yd (body, floor and flys) is Judy's personal tent which she used and tested on the JMT last month. Any tent made from cuben fiber requires an appropriate amount of special attention to assure long life. The material is clearly expensive and delicate, and should be treated with care. We are actually recommending that to improve durability, customers either order the CT5K.18 (1.5 oz/yd) cuben or a 30D sil-nylon (1.35 - 1.4 oz/yd) for the floor while maintaining the CT0.6K.08 for the body and flys. Our testing showed that using our design, this material is completely suitable for the body and flys. Using the heavier materials for the floor will raise the weight by about 3 oz. over the CT0.6 base weight.
We understand that there are variations in the product use, skill level, expertise, and weight tolerance of the customer base and want to offer options to meet those varying needs. That is what is nice about being able to offer custom made products. If there are other materials that customers would like to pursue, we are willing and able to consider those.
