i've had to go with the fat boy. mine are 500mm high by 500mm dia making them 100 litre so good for 70-80 litre boils. be a lot less at the end. i'm happy to take the lid off and stir, but will put the lid on to settle.
just getting stuff together to build mine. only got a 30,000 btu burner for now though. the bigger ones are expensive over here.
