I posed this question in another thread, no one ever commented, either to confirm or deny. The best info I have is that a bowline hitch is not reccomended in Dyneema line, that a triple fisherman's bend should be used instead. This rope is very slick, and will not hold knots well. For Amsteel, a brummelled eye splice, on the other hand, is dead simple and rock solid. So, there was a thread by a fellow who had made up a very nice looking pair of whoopie slings, and had finished the ends with bowlines. This sounds as if it could be unsafe. I want others with more real world experience than me to weigh in on this subject. If people get the idea that they can tie knots in this stuff that won't hold in reality, somebody's gonna get hurt.
