The XR4 Lite is comparable to a 3/8 scant and is now available in both head and heel ropes.  Classic's patented Coretech technology allows more weight to be packed into a smaller area, resulting in a rope that weighs the same as a traditional 3/8 true rope, but has a smaller diameter. T his type of construction also results in a rope that has more body and a longer life.  
Even though this rope was designed for women who wanted a 4-strand rope in a smaller diameter, all calibers and types of headers are using the Lite. Kevin Stewart uses a Soft XR4 Lite.
