I also use the carb cap with only flower at any temp. I find there's too much airflow without it and i run out of breath within seconds, but using the cap I take 20-30sec rips.
Pretty sure I remember reading somewhere it's better/recommended to use the cap at all times. — BlluntRapp
I tried using the elev8r WPA last night as the bowl last night, worked fairly good. The flavour was much better then the TI bowl, didn't need the carb cap. But i couldn't get full extraction after many hits, probably due to how far the coil is from the herb. — BlluntRapp
