I've heard mention heat beads on here and have found Australian Heat Beads online from BBQworld. http://www.bbqworld.co.uk/weber-barbecues/accessories/australian-heat-beads-4kg-bag.asp Are these the ones to buy and if so is this a good price? So far I've only managed to get about a 4-5 hour burn using lumpwood I've bought at Homebase. I've used the minion method. http://www.homebase.co.uk/en/homebaseuk/lumpwood---4kg-814145 Is this a good burn time for one basket? I'm wondering as I see forum members posting about leaving a brisket in over night to cook and wonder how the hell they can have a basket burn for that long.
