I have been using the Convector XL a lot these few days and have been experimenting. By using a coarser grind and filling three quarters full with no tamp I get, to my tastes, a perfect draw natively through the stem.
Have also been pushing it a bit with 14 pulses with the wand on the very tip of the cap (halfway into the wand is about right) and then 2 pulses with it inserted fully. Pause a few seconds before hitting for huge clouds. Am yet to get OHE natively but can completely vape the bowl with one or two more aggressive reheat of 8 pulses. With a torch I just heat till the tip glows (being sure to only heat the very tip; you can also come at the cap from the top moving the flame over the holes at a slight angle) then pause and hit. I think the draw speed also effects the vapor production. I get noticeably bigger hits if I slow my draw down.
This vape is fast becoming a favorite that I regularly reach for. The flavor and vapor production are phenomenal. With the super capacitor having 4 times the thermal capacity I am pretty confident one heat up would kill the bowl or allow you to sit and sip for longer between reheats.
