I envision that anyone serious about traditional Chinese swordmanship will find that group to be amazing.
In these times so much sword material has been lost due to a century(or more) of neglect, this group is part of a modern focus on conserving and preserving what remains.
One fine example is test cutting, many CMA people who know sword forms do not realize how skill in sword forms does not translate to cutting skill with a jian. A sharp sword will cut anything:

Indeed the Chinese jians cutting power rivals that of the Katana.
However cutting does not mean one is using proper technique or method, test cutting does not test your ability to cut, it tests your ability to cut with the moves of your form done at proper speed.
In combination with the two person wooden sword play, test cutting and form work, one can develop sword skill, which in turn vastly increases open hand skill in a way that non-sword people cannot understand. This is more than just having a sword form that increases specific skills, this is that having real sword skills increases specific skills. The TCSL is just awesome! I hope one day that a YMAA player could win the prize.
