What do you use now?
Well, that sounds dramatic. I hope all of your brewing endeavors aren’t so precarious.
I currently use a 20 gallon stock pot, stainless, with an aluminum core bottom. It’s fine.
Except:
-The fatter the kettle, the more wort loss when siphoning off the break/hop trub. Especially with a flat bottom.
-Even with the clad bottom, a bayou classic burner can be undersized when there’s wind (without a screen).
-Once I get a rolling boil going, boil off pushes 20% due the the large open surface area which is high unless you don’t care about your final volume.
I’m actually considering going back to a keggle, especially since it would weigh less, boil faster without the BS clas bottom, and fit better in my upstairs closet that has to hold my brewing equipment. The only reason I have a 20 gallon pot for 10 gallon batches is the above failings.
I must admit, I love how S Cerv writes. Ultimatum equals ultimatum
I have keggles on the Sabco. In my world, they work great and produce repeatable beer. It is likely that I will never replace them.
What does a clad bottom have to do with the situation you describe?
Mainly it means I have to crank up the burner to the max to get a good boil. And it makes the pot heavy. Clad bottoms are great for not burning stew, but for brewing it just makes thing inefficient. I’m semi-serious, though, when I say that I’d rather quit brewing than pay the price for a Blichmann kettle 
I’ve been using to 10 gallon megapot for about 3 years and love it. I recently just picked up a 15 gallon pot when they were on closeout from Midwest Supply. I’m hoping to retrofit them to use with a Blichmann boilcoil and the BrewEasy lid. I just need to check on the dimensions to make sure they fit.
I use a 10-gallon Polar Ware 361BP brew kettle for 5.5-gallon batches (the 361BP is from the made in the U.S.A with factory welded fittings line, not the imported economy line that is sold in most home brew stores). I use the custom brew kettle shown immediately below that I made from a 27-quart Vollrath Optio stockpot for my 3.5-gallon batches (I use a false bottom with whole hops in both kettles). I am in the process of replacing this kettle with one made from a 24-quart Vollrath Tri-Ply stockpot. I am using both of the smaller kettles with an induction range because they are both induction ready. The American-made Vollrath Tri-Ply stockpot beats the Chinese-made Vollrath Optio by a long shot when it comes to heating efficiency on an induction range. The Tri-Ply heats better on the induction range without a jacket than the Optio does with a jacket. I may turn the Optio into an insulated mash tun.

It must be the engineering mindset, but I find keggles to be horribly inefficient in terms of heating and cooling. I gave my keggle away because I blew through 4 gallons of propane (20lb tank) in five batches. Switching to a St. Pat’s 38.5 quart Vollrath stockpot-based kettle allowed me to use a Superb PC-100 stove, which extended 4 gallons of propane to 12 batches with 90-minute boils.
The induction range is a great idea, and I’ve considered it but currently brewing outside the propane burner is more convenient. Maybe in the future when I have room for an indoor brew rig.

Although, I could buy a lot of propane for the price of a good induction cooktop that can hold a large kettle.
