Hi Kurt and Andrew,
Welcome to you both and thanks for your contributions, I hope that you have not been put off by the somewhat critical reception from some here. Perhaps surprisingly, quite a few new posters start by sharing their discoveries with us, expecting that the rest of the forum will be as enthused as they are. In a couple of months, I will have been posting here for four years, yet I am still very much a newbie, indeed, only a couple of weeks ago I discovered how to make a bowline from a slipped overhand and posted it here with glee.
Unfortunately, some of our longer term members have been slipping their overhands for so long, they seem to have forgotten the amazing exhilaration of finding a new knot or method - (new to us at least, because we just found or devised it). The thrill your both felt is what drives our field forward, so keep twiddling, finding and inventing.
@Kurt, to set out to construct a knot with specific attributes demonstrated a deep understanding of the nature of the cord and the flow of forces within a knot structure - I hope to see you over on knot theory soon, your ideas will be welcomed.
@Andrew, you have a skill which I seriously admire - the ability to develop better methods of constructing a knot. The structure and function of a knot is important in defining its abilities, but the tying method makes the critical difference between a knot being in popular use or simply only used in knot boards. Obviously you cannot have a tying method without first having a knot, but having a knot (even a potentially good knot) without a good method, is as useless as having a poor knot that is easy to make. The ability to upgrade one knot into a superior one in a simple or memorable manner is a true asset to our field - again, I hope to see your skills being put to task over on knot theory before too long.
As for the knots/methods themselves, although good, they are unlikely to set the world on fire because they do not appear to satisfy a daily or otherwise popular need, but this should not disappoint you, because what you have both brought is the bright flame of interest that this place and our field so desperately needs. Passion is contagious, so bring it on the pair of you - more thoughts, more ideas, even more musings and please don't be worried about kicking up some dust (and grumbles) in the process.
Thank you both.
Derek
