They are relatively solid and just a slight twitch with use and you will be wondering where your stylus has gone. Since all of my cartridges have styli glued to the end of a boron rod the danger is quite real.
I use the Lyra fluid and a dense artist's brush which also allows you to clean accumulated dust off the cantilever. Magnification is always helpful. I use loops. With the way I play records I might have to clean the stylus once a month.
