The default tool head for TAZ 6 (Single Extruder v2.1) used a 30W cartridge (EL-MS0377). The newer SE Tool Head moved to the 40W cartridge.

My _suspicion_ is that if you installed the 40W cartridge, you’d have to modify the firmware telling it to provide more amps in order to notice any difference. I’d personally stick with the 30W one.
