I plan on doing the 50/50 burger here real quick. One ppund of burger, and one pound of bacon, fried, crumbled, and mixed with the burger to make patties. Topped with bacon, and thick slices of cheddar.
Otherwise, I use 60/40 burger, a couple eggs, bbq sauce, wosterchire, garlic powder, onion powder, fresh cracked pepper, kosher salt, and some red pepper flakes. Good stuff!
