Is there a considerable difference when heating to a boil between a 5mm sandwich bottom or a single ply pot/kettle. I am going to full boils and have the $ to buy, just trying to make the best decision I can. I also posted a few days ago about burners and was wondering sq-14, sq10, or banjo? I'd like to get a few boils out of a tank of propane, but I don't wanna wait an hour for the water to boil. Which brings me back tho the original question, would having the thicker bottomed pot/kettle decrease heating times significantly? Or, would it be just fine to have a Bayou Classic singly ply pot. I'll be doing 5 gallon boils with a 40qt pot.
