You know that ribs are such a thin slice of meat anyway... anything you use as a rub is going to really effect the taste. I don't even let mine sit in the fridge overnite. I rub em down and slam them on the smoker. Plus... I like the taste of good ol ribs. Marinades tend to change the entire flavor of the meat. The salt cure will have it tasting more like ham than ribs. Some folks like it that way. You may want to experiment with it and se what you come up with. Cut a few off the end next time and come up with a marinade.
I have only done a marinade on ribs 1x... it turned out good, but could have got the same flavor and results our of a roast. I wanted a SW flavor and the only meat in the fridge was a rack of spares. Marinated in 2 cups of hot salsa, juice from 1 lime, salt, little bit of veg. oil, and some fresh cilantro.
The flavor was acctually quite nice, but definately not a classic rib.... meh
I'm with Piginit on this one. I used to rub my ribs the night before and let them sit in the fridge but now I light my pit then some in and rub them down while waiting for the pit to come to temp.
Give it a try and see how you like them.
