i ive been wondering, since i bought a fancy vector stand up torch for my new hmk curve, this thing can run for over an hour on a tank, and butane is cheep...do you guys just leave your torches on or do you switch it off between hits? i used to switch off between hits because i used to use a tiny pencil torch that only held about 15 minutes of fuel, tops...with this new torch it almost seems like it would be easier to leave it running till 'done, but i was curious about the current customs of the local oil heads...
