Hey Tim, if you haven't done a beef clod, I recommend it! We hosted an engagement party for our oldest child in July. I decided to do a couple of pork butts (10 pounds each) and a shoulder clod (21 pounds).
I put the pork on the lower level of the WSM, and the beef on the upper level. For the beef, I carved out the flat iron portion so I could remove it from the cook at the right time. The "petit filet" folks mention is a unicorn, you just aren't likely to find one anymore in a packer, the processors are removing these due to demand.
Please excuse the goofball in the picture below, but here are the raw materials.

My favorite rub comes from this forum, I used "A butt rub, for Jane" on both. I didn't sauce either of these but put a version of No. 5 and a Char Sui on the side of the serving table.
The flat iron portion has got to be the single best thing I have ever taken off my smoker!
The Clod Heart was dang near as beautiful.
The pork turned out just fine from the lower level, just needed a little more time once I had the beef off.
I would do a clod again in a heartbeat. Excellent price point, large volume. Other than watching a video to extract the flat iron, it is a super low skill level cook. I would step on the brisket that I've tried to cook (all 4 times) to get to this clod!
The party goers loved it, but I think the compliments might have been alcohol induced!
