i think chops mentioned that they dont get as hot as his other metal knobs.
it also depends on the finish/texture of the knob. ive had metal knobs that got hot but not super hot in the summer months like the twm satin knob.
but then a polished momo got scorching hot.
if you're worried about hot/cold, check out the twm specter. it's weighted brass core with delrin. very nice.
