Oh I forgot bama.... I'm a 275 guy and have a lot of the same problems with higher temps like some of the other guys that do it.
U might remember I was preaching and showing hot and fast when it was a practice to be ridiculed. Once People got turn on to my results they started pushing th envelope further than I chose to go as I had already been there... I never have good luck withsustained super high heat like above 325. I can do short bursts but have the same concerns as you. And I pretty much am credited with the Reintroduction of hot and fast.... To such an extent... Heck.... I don't even think my temp is considered hot and fast anymore. I miss u bama!!!!
