re: Suggestions on marinating Ribeyes?

First things first, buy a quality piece of meat. No marinating. Putting salt on a steak starts the liquid extraction process, so I season right before I put on the grill, or in my case the pellet smoker set to 300. Room temp steak, hit it with some weber steak and chop(just salt, pepper, onion and garlic powder), then on the grill. You may have to add some seasoning when you flip.

That's how I do mine, but there are many ways to do it. To answer your question specifically, I don't marinate.
