Hopping into gas chat to say that once I got whip-it! brand butane I never went back. Prices are decent, the gas is really clean, and my lighters love it. That and the little purge tool and the only problems I have with lighters is poor QC on new ones from the manufacturer. I went through 5(!!!!) Yocan Temporal Torches before finding one that worked properly and didn't leak.
On topic, the Vertigo Carrera is far and away the best I've found for the vapcap. That wide flat flame wraps around the cap when held perpendicular, and is an absolute beast for heating. I found, even with it turned down, I had to start heating closer to the tip or risk combustion. I have two and they've been reliable. (As expected from Lotus Group lighters.)
But really I just use my induction heater these days for the vapcap and stem devices. The easy button has won me over...
