So does that mean that you are literally hooking on the boom to the testing wall? If it is
being hooked on, though I'm not sure it may be a good idea, can't you get rid of a base altogether? Instead can't you bend the tension members in U-Shape in a jig, with the bend of the U being where the base is, and the forks of the U being the far end of the boom, and then just hook the U on the J-Hook?
Also, the wiki needs to be updated to reflect rule changes and to guide people like me
