shamwari, i think even with hands of steel ul cut them off, if not its not tight enough, but both knots are tried tested and well proven, i think with a good bobbin theres less room for "error" regarding the pr, where as if you tighten the fg without doing the correct steps you may get some damage on your braid...that fg needs to bite properly, i use a japanese knot puller, which is expensive but well worth it!!as you say both awesome knots, pulled fish on both and 100% confident in either
