Nylon is the strongest synthetic material commonly used for DIY ropes. It has a memory for returning to its original length, making it best for absorbing shock loads. It's the best option for hauling, lifting and towing. Nylon will last four to five times longer than the natural fibers because it has good abrasion resistance, good UV resistance and it is not damaged by oil or most chemicals. The Diamond Braid construction has the best lifespan of all the braided ropes.
