You could read back on the thread, a couple of years ago there was a lot of discussion here about beads on the torched unit. The coiled unit heats up much slower than the torched one. With the torched heater this creates a temperature differential between the heater body and the enclosed beads and different expansion rates can cause breakages.
My experience with beads has been useless with my heater lol. I went against advice and tried to install 3mm rubies in my torched heater. Unfortunately 3mm doesn't go past the spikes so they just fill the small void between the bottom spike and the screen. I didn't notice any difference so took the beads out and never thought about it again. I don't mind a quick reheat if necessary.
