I'm doing my first spare ribs cook for Super Bowl Sunday. I'm feeling pretty good as far as methodology goes, but I don't have a rib rack. Any recommendations for one? This particular cook is for a small-ish group (8 adults and maybe 4 or 53 or 4 of the kids will eat one rib,) so I could probably get by without a rack on the WSM 22.5. However, I do some larger events from time to time (20-40 adults), so I figure I might as well go ahead and get something that will meet my needs long-term. Thanks in advance for the advice.
