1.
@villekille2 has made some improvements for the Helios regarding the algorithm to maintain the flavor even better when sessioning. But this one is not temp controlled, it's power controlled via the knob. If this thing is running and heat soaked it's hard to overwhelm the heater... You would choke and cough - and/or combust finally
2. Yes, you press the boost button as you like. You can also adjust the boost power and save it. I think max. overdrive is 120% of the bulb wattage.
3. I'm not sure what the latest iteration of the big Helios is capable plus the latest generation of bulbs. Think it's cut down heat up to around 30-45 secs.. Hope
@villekille2 can chime in soon.
About glass bulb breakage, never heard of that before. Then, the bulb is installed in a SS cylinder that has a screen on top of it. On top of that you place your SS chamber that has two more screens. Everything that would pass all these layers would need to get lpast another screen on the base where the air is drawn into the tubing. Then all the way up the tube... If something like that happened, you would have stopped drawing before it goes there. Ultimately, you could use some hemp fiber and put it in the tube as a super fine filter. Would not have a concern about that.
