Well verdict is in. My brewing partner, D-boss, and I will be cutting the pony tomarow and adding a weldless bulkhead, for use as a HLT for now. I may in fact borrow it from time to time to boil a 5 gallon batch. Since I only make 5 gallon batches, and have that, and a non valved aluminum turkey fryer pot for choices, or 16 gallon keg, which tomarrow will also be valved. Honestly the aluminum 8gal pot heats faster, and cools quicker, and have had no problems with scorching. Only thing is alum is a no no for some people, and I havnt tried the batch yet I made in it. We from time to time, do double batches, we are finally getting enough Mash tun coolers, and boil kettles, burners, and hlt's together to do this in a fair amount of time. Last time was 9 hours for 2 seperate 5 gallon batches. But we also brew independant of each other at our own houses, as finances dont always make brew day fall on same week. I would not imagine boil over potential any worse than the alum pot. My boil had leaf hops, so it wasnt to violent, and had no issues, didnt even come close to boil over, with 3 inches from top.
After 1 hour boil, level was low enough for chiller, and cooled FAST.
Edit, Just tried my batch from aluminum pot, tastes wonderful, im racking to secondary tomarow, but will end up a good beer I promise.
