Paul is correct about what those points can and will do to an unprotected surface, especially when you consider the weight of a BH kit. I have a set (I use 3 for easy leveling) under one of my amps and use the disks with the divot or hole in the center. With no kids or cats I haven't had a problem, it has even survived a few SoCal earthquakes, YMMV.
There are those who say that using the disks gives up the sonic advantages attributed to the use of spikes in the first place. I simply don't have the ears or listening skills to discern a difference...that's another rabbit hole.
Happy assembly and enjoy the BH experience, no matter how you decide to let the kits breathe,
Karl
PS. Another sacrificial surface idea is a cutting board, many choices.
