Still trying to hone my heating method. I try to hold or wiggle the torch so air HAS to pass through the flame when I draw.
The Piro seems designed for a single torch with a thin long flame.
My triple torches causes near instant extraction but puts me in the danger zone. I've been combusting and trying to find the best flame to vapor ratio without pushing my luck and not wasting butane.
The triple triangle torch seems to cover the area over the input hole for me to heat up the incoming air.
Most of my lighters are Vertigo, Which can be finnicky when the elements get hot.
