I get your point about thermal mass / heater capacity. I didn’t make it clear that I was thinking more of battery powered portables, not desktops / ball vapes. I wish I was as successful as you with my TM2, but mine didn’t prove to be an upgrade.Op's premisse was:
The ball vapes heating method (the strengths mentioned by @Shit Snacks) have nothing to do with running hotter.
A device with a strong heater and good heat retention, in particular convection vapes, can extract quite successfully and quick at low temps. With TM2 at 3 I can extract most in say 4 hits, at 4 in 2. Higher in 1.
