Just realised I misread, sorry about that, have a v2.4 not a 0.2, I'll talk about my machine though, sorry about that!

There's less thermal mass on a lot of bed slingers, at least on my franken-prusa, it's just the PCB and the build surface vs what like 3-4 kg of aluminum that's the voron build plate.

I have a 720 w 120vac heater on mine, it's limited to run at 60% max (There's documentation about max heating, don't want to warp the bed) A v0.2 will heat up faster than mine, not even sure you would get much benefit from an ac heater at that size, the prusa heated bed is perfectly capable of hitting 120c no problem on 24 vdc in 5-10 minutes, 60c is super quick, been doing a lot of PLA on it lately and it's pretty much at print temp after a quick bed and nozzle cleaning, totally imagine a 0.2 would hit print temps super fast. Still worth a heat soak imo, but depends what you're printing, I don't bother with PLA, petg, just a quick preheat and then I send it.
