i used to make my own rub, but kinda like webers kc rub better. bought it at sams club. you can inject with apple juice or vinegar. seems like 225f/hr/lb . sometimes finish off in the oven at 350 or rotisserie to get outside crispy
I drill holes connected to each other. It m as kes a ton of slush, but I find removing slush easier than sawing thru ice. Do need the saw if hokes aren't connected properly
