QUESTION: What is the difference between UL and ULS Bo-Tuff?
ANSWER: ULS has a 50/50 woven fiberglass inlay (scrim) that provides cross strength (90 degrees to the longitudinal axis). This scrim layer will give strength lengthwise to help reduce longitudinal cracking. If you are using a radical design or have experienced cracking, for instance, around the holes drilled for your limb locking hardware, ULS may be considered. For most designs, however, UL and ULS work equally well.
